Hello,

I would like to create button in CRM and this button, after click, shows me the widget of my form I made in Creator. 
I was trying to add widget in setup of CRM (where I used external URL. url of my creator form) and connected it to the button in CRM. everything worked well, untill I clicked on the button in CRM and the page showed error, that Connection refused, and I am not able to use my form in CRM widget.

What is my possibilities to acomplish showing my creator form in CRM custom button?
There are some restrictions:
1) the creator form should not be visible publicly.

2) The Form must be shown as widget, not as separate tab / window.

Thanks for any ideas.
