I just cant find the way to connect them.
Currently there is no way. You have to use some twisted way to get it. Here is how I solved it:- I signed up on brave creators and added my twitter account as a creator channel. It got verified in a day. We can connect the uphold wallet to the creator account. Then I browsed my twitter profile from phone. It will show an option for tipping. As I am a verified creator now, I can receive tips. So I tipped the whole amount to my twitter account (I tipped, myself). This BAT eventually reached my uphold wallet through the creator account.
