when a user requests access to your private photos "button access request" is no longer displayed, but it happens very often that the reason for a careless user who requires access to not accept or does not read the request and therefore does not accepts. This means that if we want to see private albums and the user wants to authorize it after long chat must reread all the conversation and find the link to authorize access, and this is really uncomfortable.
I think the button "request access" should always be present when the request has already been sent.
