You need to adjust the MPCLogin.test.tsx . You need to mock the currentChain to be on Gnosis Chain such that the buttons are enabled.
You could also add a test case for non supported networks to check that the button is disabled and the hint is shown.

Just 2 small nits in the test. Otherwise LGTM!
