Use pop-up drawer when interact with mobile app

[j4w3ny]

Describe the usability problem Currently when a mobile app connecting to Metamask Mobile, it has to jump to the Metamask Mobile app and sign the request. I think it could be simplified with one pop-up drawer to showcase those info and confirm the request. (Like Google Pay/Apple Pay)

Expected behavior

1. App created and request to connect to Metamask.
2. A pop-up drawer intent shown to user to confirm request.
3. Once it confirmed/rejected the request, send a callback to app.

User impact | Usage frequency | Feasibility scores Not a important request, but it will surely improve the fluency of user experience.
