Anyone used EasySMX T39 Gamepad on Linux?

I have found the EasySMX T39 and T39 pro for 15 and 16 euros accordinally and I'm thinking on buying the pro but I don't know if it works on Linux. I have a reason to doubt that it is compatible (even tho most gamepads are) because in the official showcase video on YouTube, the account of the company replied that it doesn't work on Android and Steam Deck support isn't mentioned anywhere either.

Has anyone bought and use it on Linux?
