Why is Angular returning ZoneAwarePromise instead of the actual value?

I've been struggling with a coding dilemma for quite some time now and I'm in need of assistance. The issue at hand is related to a method that's returning ZoneAwarePromise instead of the desired string output. Let's take a look at the code snippet below.

retriveRes() {
      /*
        Within the subscription callback, an asynchronous method (httpTranslateToAr) is being invoked.
        However, it's returning a ZoneAwarePromise when we actually require the translated string as the output.
        Despite my efforts with async and await functionalities, I haven't been successful in removing the ZoneAwarePromise from the equation.
      */
        this.userSubjectOutput.subscribe((res) => {
           let manipulatedJSArr = res.map((step: any) => {

            return {
                step: step.step,
                content: this.httpTranslateToAr(step.content), // The problem lies here, where the content value ends up as a ZoneAwarePromise
                exercises: step.exercises
            }
           })
        })
    }
/*
      I've been tinkering around with this method but I can't seem to figure out how to fetch the API response 
      and provide a specific value for use within the retriveRes method.
    */
async httpTranslateToAr(str: string) {
       
        this.openAIparams = {
            messages: messages,
            model: "gpt-4",
            max_tokens: 700,
            temperature: 0.3
          }
        await  this.client.post('https://api.openai.com/v1/chat/completions', this.openAIparams).then(
            client=> {
                console.log(client)
                clientValue = client;
          }).catch(err => {
            console.log(err)
          })
          console.log("lol")
          
          console.log(clientValue.data.choices[0].message.content)
          return clientValue.data.choices[0].message.content // My aim is to have this value returned without it being a ZoneAwarePromise
    }

Can someone guide me on how to modify the content in the map function so that it only provides a translated Arabic string rather than a ZoneAwarePromise? Any insights or explanations are greatly appreciated! :)

fetchData() {
  
   this.processedUserData.pipe(switchMap((data) => { // Using switchMap to wait for the manipulatedUserArray to be constructed before moving on to the next step
           let manipulatedUserArray = data.map(async (item: any) => { // Making the function async in order to return an Array

              return {
                item: item.item,
                details: await this.fetchTranslatedData(item.details), // The details will be a value, but the entire object {item, details,...} will be wrapped into a promise due to the async nature
                tasks: item.tasks
              }
           });
           return Promise.all(manipulatedUserArray); // Converting an array of promises into a single Promise with the resulting array. This big promise will be unwrapped using switchMap
    })).subscribe(output => console.log('Process the result accordingly ', output))
}


async fetchTranslatedData(text: string) {
       
        this.translationParams = {
            messages: texts,
            model: "gpt-4",
            max_tokens: 700,
            temperature: 0.3
          }
          const translatedResponse = await this.translator.post('https://api.translations.com/v1/translations', this.translationParams).catch(error => {
            console.log(error)
          })
          console.log("haha")
          
          console.log(translatedResponse.data.choices[0].message.text)
          return translatedResponse.data.choices[0].message.text // Since the function is async, any value is wrapped in a promise and cannot be directly accessed
    }
