I have embedded a Desmos activity into my Canvas course using the following HTML script.

<iframe style="border: none;" src="https://student.desmos.com/?prepopulateCode=CLASS CODE GOES HERE"...

This successfully embeds the activity, which is great. However, whenever we try to sign in to the activity using a Google account it returns an error. Upon investigation of the developer tab I found that it's an error with the SameSite cookie being set to Lax, rather than none, which means the activity is being blocked from interacting with the Desmos site.

Has anybody been able to work around this problem with Desmos or another app?
