Nostur must be activate too ? Because in Damus I can but in nostur I don’t have the ⚡️in the reply.

I think their workaround is that you have to add the ⚡️ reaction and it becomes a zap button i am told
Thank you finally I found the way “you must put it manually”
did you receive a sat from me?
i ‚liked‘ your post with my ⚡️ button 
Yes I received, thx for the sat and zap zap zap now with your ⚡️bottom.
Yes you say me the way !! Thx a lot of it is a little complicate because normally you see the icon and drag and drop but with the ⚡️you must write the emoji in reactions.
