calling .next on Observables is not allowed

I am currently experimenting with data sharing between two sibling components by utilizing an injectable service. Within my injectable, I have implemented an observable in the following manner:

@Injectable()
export class DatasService { 
    message: Observable<string> = new Observable<string>();
    changeMessage(){
        this.message.next('Arpita'); //Property next doesn't exist
    }

    changeMessage2(){
        this.message.next('Ankan');
    }
}

However, when I replace Observable with Subject, everything works smoothly. Is there a way to achieve the desired functionality while sticking to using Observable instead of Subject? As a newcomer to reactive programming, I find myself feeling confused about this.

Opt for a global variable over injectible to ensure easy access throughout your project. 1. Add a property to the DTO. 2. Import it into the specific component where you need its usage. 3. Define a variable of that type in the constructor’s parameter. 4. Utilize the variable for access.
