As an integrator I would like to setup accounts easily for testing

As a Test Engineer, I would like to test my application, but I can not do it, because connecting to a site requires handling Browser Extension without Web view.
I would like to have the possibility to specify a site manually, so when the test starts, I can test my app as if the extension is connected.

I can connect to a site from the extension itself, but I can not do it using the web view,

Would be possible to also store all this config somewhere ( JSON config ) and import it? that would help a lot for automation purposes!
