Blocking Image File Transfers via AnyDesk with Sophos Endpoint X Advanced

Sophos Endpoint X Advanced 
I had implemented blocking mechanisms for image file transfers through the internet, USB drives, and uploads via URL links. These measures are working as required.

However, we have encountered a challenge with AnyDesk software.

Despite our efforts, image file transfers via AnyDesk's file manager are still possible and are not being blocked. Any solution to effectively block these transfers to ensure the security. 

thanks in advance.
