Change network and add token in unity

Hi there. I want the user to change network and add token functionality in unity. Is it possible?

Nothing is impossible in this world, my friend.

Being able to request that the user changes network or adds token would depend on the wallet e.g. MetaMask, and I’m not sure you can do this through WalletConnect or say the MetaMask mobile app. What sort of wallet connection are you looking at?
