Connect Xbox Controller S to Huawei P20 lite?

I would like to buy an Xbox Controller S Now the question is wireless or does one need a cable

Or generally what (I think because with the PS4 controller was not.)

That generally can't be connected to the Huawei P20 lite controller?

Do you want to use it only for the mobile phone?

Yes

Then there are two possibilities: Either you load the program Octopus for 1 euro down and program the keys for games or you buy yourself a 𝐻𝑎𝑛𝑑𝑦𝑐𝑜𝑛𝑡𝑟𝑜𝑙𝑙𝑒𝑟, so no controller is required and designed for mobile games.

Now have a controller with OTG cable but it does not respond what do I have to do now?
