I have a question regarding private forms in custom teams app.
We have a spfx teams app which shows a list of provided microsoft forms.
We use a task module for showing form inside MS teams.
Also we have a list of private forms (for users from organization only) and we are struggling with follow problem:
Public forms work fine through task module because any kind of authentication skipped here.
Private forms work in Teams mobile app (Android and mobile) and provides login view (page) for user first time. Web version and desktop version it doesn't work. It's related with iframes usage.
I found that that SharePoint Forms webpart and Teams Forms tab use special URLs and parameters.
The mine question: How we can integrate MS Forms with teams app (through task module) or another features? Any help/information will be really useful.
