Add a parameter to tawk.to to hide the chat widget

I am using the tawk.to chat widget on my home page. The home page also includes an iframe which injects the KB as an FAQ:
Go to https://russianmathtutors.com and scroll down to see the green KB.

I am calling the iframe like this:

But, as you can see, there are now 2 widgets, one for the main page KB and one for the iframe KB. Seems like this is a common use case, where a web page wants to use the KB as an FAQ, and you must know that a home page should have an FAQ for easy reference.

I propose adding a query parameter on the request hide the chat widget like this:

        <iframe style="border: 0; width: 100%; height: 100%;  min-height: calc(100vh - 120px);"  frameborder="0" src="https://russianmathtutors.tawk.help/category/for-students?no-widget=1"></iframe>
