After successful connection of Metamask app, it is not closing app (metamask) and remains on metamask.

**Expected behavior**
It should close Metamask app itself after a successful connection.

No file, test, or entry point is named. Start by reproducing a successful MetaMask connection on the mobile app using the attached video as a reference, then trace the connection flow; it is done when MetaMask closes automatically after a successful connection.
