Get Acumatica HTML for creating custom dialog window

Hi,

I have application which is implemented via html,css and javascript

This application  allows to create a form that looks and feels exactly like any website,

It opens this form in browser and calls one API for further work

My goal is to do same for Acumatica

Is it possible to insert this form to Acumatica window ?

For this I need to understand if Acumatica API supports html page dispatch with which I could work.

I mean now it opens just in new tab in browser, does it possible to pass this from to Acumatica window like this ?

Is it possible to do that without work with screen graph by adding new element, adding new screen and writing new business logic in Acumatica ?

I have ready API and I just need to call it in new Acumatica window not new browser tab

Thanks in Advance
