Glad to see this functionality coming soon for JS binding.
Could you please also make some relevant examples for this part?
It will be great to know how to see all pending and/or completed http requests, which application send (as we can see it in the browser "Network" tab).

Hey @StanislavKharchenko. The documentation will be updated soon for the BiDi modules. Meanwhile, I have added tests to this PR also. You can have a look at them to get some idea. Though they aren't written from a user perspective but more from a testing point of view.
