Nest Camera via URL

I have seen a lot of posts stating to use a URL to display a feed from a Nest Camera.
I set that up in Nest, and have the URL generated, but am unable to make it work with a dashboard tile.

Secondary to this, I want to get some other cameras, (Wyze, for example), but am concerned the URL issue will still plague me.

Any help would be appreciated.

Try it on a browser first. If you can't view the video then it won't work in the dashboard. I believe most of the people using snapshot with a 1 second refresh on an image tile. You can also try iframe tile.
