Panda game pro - pes2021-ipega9157

Hy guys i’m new.
I hope to find help to solve my problem. I have a samsung galaxy tab s7 with which I play PES mobile. In order to play better I bought a joystick, specifically an ipega 9157. To map the keys I chose the panda game pro application. I have followed all the settings to the letter but something is not working. When I try to pair the joypad with the panda application, the latter recognizes the pad as a keyboard, making it impossible to map the keys. I tried with another joystick terios ZM 16, but I have the same result. Can anyone advise me on a possible solution? I also tried the octopus pro application, but this also pairs the joystick only as a keyboard. Thanks for your patience
