Add button to prompt adding more images on IOS

[max-feldmann]

As an IOS user I have limited the access to the pictures on my phone. However, when using the rocket chat app, it only prompts me to add more fotos ONCE during a session. I have to completely shut down the app an reboot it to be able to do so.

Suggestion: Either ask every time a user opens the media feature or add a simple button/link to trigger this. (Both are common and valid ways other messengers like slack, teams or whatsapp solve this).
