Need help with my firebase project and storage access links to authenticated users

I have a firebase project where I have some authenticated users using firebase authentication. What we are doing is when a user leaves or gets de authenticated his/her file(say his image) in the storage also loses access i.e the permanent url becomes invalid even thought the backend isnt deleting the file, and when the user joins again they cant access their files. How can we do so that the url doesn't become invalid when the users gets de authenticated or to find a way to check whether the url's 'token' has expired or not
