I’m not a Creator, but I think the first thing to do is get a Gemini account and get it verified (I have read at several different places that Gemini can take much longer to verify than Uphold). And in the meantime, you could post a new topic under Brave Rewards > Publishers > tag of your choice asking for advice from other Creators, or if Support could point you in the right direction.
There’s a thread that talks a little about it here, too.
Edit… maybe there is some information on this when you sign in here, @lanceuppercut, too…?
