Unable to use login in zoom app when app had embed iframe

Zoom Apps Configuration
Zoom app loads an external web page.

Unable to use embed feature within zoom apps, where the embed iframe can also have a login.

Microsoft sharepoint url is embedded within a page in zoom app, while loading the embed frame asks for login (since the user needs to give access to the external link, in this case microsoft). But click action to login does not take user anywhere

How To Reproduce

  1. Create a simple zoom app which loads a html page.
  2. add a sharepoint link (video link) to the page using embed URL (whichever link that may require external login to view the embedded video.)
  3. Now load the page within zoom app and go to the page, you will see a login button for microsoft (or respective external site). but login action does not take user anywhere
