problem avatar

Hello, I chose to use Ultimate Member because I also use WP Foro on my site and it syncs so it suits me very well :). On the other hand, I would like only me to be able to add the avatar of each user via a URL. I’m using the WP User Profile Avatar extension so I can add the avatar via URL (I do this because it’s a Habbo.fr fan site and everyone has their avatar on the game, if I put the url of the image via the game, the player gets their real avatar, it changes on the site as soon as the user modifies it on the game). I managed to put a default avatar on Ultimate Member but it does not take into account the avatar that I add thanks to the WP User Profile Avatar plugin. How can I make the plugin take the avatar into account ?
