"Browser Not Supported" Error When Embedding in Microsoft 365 SharePoint

edited 06/14/22 in Add Ons and Integrations

I am using the smartsheet "Embed Code" link under "Publish" to place into a Microsoft 365 SharePoint page.

I place it in an "Embed Code" Web Part and the following "Your browser is not supported" message comes up even through I attempt to view it in the latest versions of Chrome or Edge.

Am I missing something simple?
