What happens to Powerpoint embedded video playing after IE 11 is removed from M365/O365 apps?

Powerpoint relies on IE to play embedded videos in slides.

• Beginning August 17, 2021, the remaining Microsoft 365 apps and services will no longer support IE 11.

so what happens to the Powerpoint? how will people play embedded videos in slides?

will for example Powerpoint use Webview 2?

that blog post suggests to use the new Microsoft Edge, and I already use it, it's perfect.

Webview 2 is based on the same engine, Microsoft's custom Chromium engine.
