from the browser you can go to:

https://mostr.pub/.well-known/nostr.json?name=bot_at_seal.cafe

And it will give you a string (fedi uid) that you can search for:

79c2cae114ea28a981e7559b4fe7854a473521a8d22a66bbab9fa248eb820ff6

Does this string work in damus? It does in iris and would expect it should find it if you have mostr.pub in your relays.
