Someone tried subbing to my community from another instance, and the sub is pending. I have no idea how to accept this. Any ideas?

So basically I created !oldweb here on lemmy.ml. Someone from another lemmy tried to subscribe and it told them the subscription was pending.

I'm on mobile currently and can't see anywhere where a request might have come in for me to accept. If its only visible on desktop that's fine, but I'm not too sure if I need to be accepting this or how it works.

Any help appreciated!
