How to add a new network that is not already listed?

[vivek-consensys]

Is your feature request related to a problem? Please describe. I would like to add a new network when setting up Metamask

Describe the solution you'd like I would like to add an additional step in adding a network in the metamask extension, where you will have to include:- Network name, RPC URL, Chain ID, Currency Symbol and block explorer URL

Describe alternatives you've considered There is not much alternatives you can try, metaMask.acceptAddNetwork only works when there is a prompt within metamask.
