How do I stub Google Oauth when making requests with Cypress?

I'm trying to use Cypress for testing my Express, Google Oauth2, React/Redux app & have hit a problem where if I try to hit my API I get a Status 401 - Unauthorized error.

How do I allow Cypress to hit my API and create a new ask in my actual database with testing code like:

cy.request('POST', '/api/ask', example_ask);

Is stubbing the Google Oauth the right approach? If so how do I even do that?
