Show different Websites in Form


I wanted to ask if it's possible somehow to show different Website inside a Form.

I have this form which shows some Project-Infos and under the DataTable i would like to add a part where the Timetable from Microsoft Planner is Visible which has the Tasks from this Project.

Is it possible to actually show different website on a Form ?

Kind regards,

Dear @Dario_Chiga,
You can place an iframe onto the form with HTML control - HTML iframe tag

Thanks.. Seems to work with one Exception

Is there a way to work aroung this problem ? are there any parameters i have to give?

The translated text is :

" denied the connection."


Dear @Dario_Chiga,
Is it a different domain from the current site/other pages that you load? Most likely cross-domain pages are not allowed.
