How do you conditionally add condtions to a Firestore query in with the JavaScript SDK or React Native Firebase?

For the sake of handeling infinite scroll, I created a function that add conditions to the query according to the desired behavior:

  const queryDocs = async (behavior: string = 'start', limit: number = 25) => {    let augmentedQuery: Query<DocumentData> | CollectionReference<DocumentData> = query    try {      if (behavior === 'start' || behavior === 'limited') {        augmentedQuery = augmentedQuery.limit(limit)      }      if (behavior === 'next'&& lastItem) {        augmentedQuery = augmentedQuery.limit(limit).startAfter(lastItem)      }      const snapshot = await augmentedQuery.get()      if (behavior === 'start' || behavior === 'next') {        setLastItem(snapshot.docs[snapshot.docs.length - 1])      }      return snapshot    } catch (error) {      throw functionError(error, 'queryDocs', [behavior, limit], 'useCollection')    }  }

I get the following error:

on queryData("start",1) in module useCollection: Attempted to assign to readonly property.

Can we take take a previous query and add a .where or .limit?

Is there a solution to handle conditional queries?

Thanks

Edit: As Doug stated in the discussion, it is perfectly possible to chain queries like this. The error comes from another source. This code was into a shared package that was recompiled from TypeScript to ES6 and then used in React Native. After merging all the code into the React Native directory the error changed. I had a request to create a composite index with the link to do so, what is quite straightforward.
