hey guys does anyone want to team up on ranked cuz im kinda struggling on Platinum I

My favorite Game is Mobilelegends l have been playing this game for 3years tha't Why l want to try the Advance Sarver Ahways cheering MLB

So I got a bluetooth controller as a gift but as I was looking for keymappers, either they were not free or they aren't working as i would like them. And I would really like to use it for some games that do not have "built-in" controller support, but because they don't have that much buttons they would be easily mappable. Thank for the replies in advance!
