Is there a way to convert an array of objects with the following structure:
{
id: number,
data: Observable<string>
}
into an array of objects with this structure:
Observable<{id: number, data: string}>
using only RxJS operators?

After analyzing the information provided, it seems like this is the solution:
const category = new Category<string>();
// Sample array
const itemList = [
{
id: 1,
info: of("something")
}, {
id: 2,
info: of("somethingelse")
}, {
id: 3,
info: category.asObservable()
}
]
// A function that transforms {id: number, data: Observable<string>} into Observable<{id: number, data: string}>
const transformData = (itemList) => itemList.map(item => item.info.pipe(map(data => ({...item, data}))));
const transformedArray = transformData(itemList);
