gravity form not working on popup

hi there,
i wanted to use a poll functionality provided by gravity forms on the popup. unfortunately, it seems to not work.
gravity plugin's icon normally shows up on the visual editor next to 'add media', but when i'm trying to add a popup message, gravity form's icon doesn't even show up.
is there anything that could be done to get it working? i basically would like to show a poll on a popup window.

the test popup is on a specific URL


PS. with conditional logic enabled, the form doesn't show up at all. currently it does show up, but looks weird and it's working..
