I am facing issues while integrating SharePoint with Ignition

I am trying to integrate the SharePoint with Ignition Perspective using Inline Frame . I have given the src = "link:embed=y" and set referrerPolicy as "unsafe-url".

Iam getting error "abc.sharepoint.us refused to connect"

Any help is appreciated. Thanks in advance

Sharepoint has to be configured to allow frames, not Ignition.
