How to know other users displayName and photo url using Firebase?

I'm developing a review site. I'm attempting to show a poster's displayName and photo, which means whatever people login in or not, any guys can see the poster's displayName and photo. The poster first log in and then post a review. other guys can see the post content, the poster's displayName, and photo url. How can you achieve it with Firebase Auth and Firestore?

I know that I can do it by using getUser or getUsers function from this ticket. How to retrieve another user's info like email and displayName in Firebase?

However, those functions seems to be for admin so it's not good to use it in the above case due to security issue.

Any advice?

Firebase admin SDK is only to use on server side. If you want to have a poster display name and photo, just add it to a post he creates or create a collection with a poster's information in it. So when you get a post with owner uid you can again fetch data with poster information.

I recommend having first option because it needs just one read for users to make. And like I said in comment if user change some think you can find all his posts and change his display name or photo there. Feel less reliable, but in reality you don't want to have 50k reads instead of 25k out of poster 5 posts.
