Get the overlay raw data from GET url

Hi,

I want to know if there is a way to ge the raw data of an overlay.

because i wan't my  stream chat interract with my website.

like i got a poll, and on my website i have live feed of the poll result vote with a custom ui interface, and not the embed poll design from botisimo.

I don't want alll the feature arround botisimo overlay, i just wan't the data and i manage how i display and where.

Do you know if there is a way to achieve that ?

I try to load an iframe of the overlay, then run a js script to read the data from the iframe. But i'm stuck from the CORS error (cross domaine error) if you know what i mean.

thank you all !
