I was testing the new free Lucid integration in Canvas, in our beta environment. I noticed that it’s not really fully integrated as far as course copies.
For example, if you have an embedded whiteboard on a page, and you copy that course to another teacher, the other teacher just sees this in their copy of the course because they do not own the whiteboard:

similarly for assignments, it technically works a little better, walking the new teacher through requesting access from the owner, but this should be automatic. Permissions for lucidchart/spark boards should mirror the canvas permissions. If a teacher is added or a course copied to a new teacher, or a whiteboard copied from one course to another, it should handle it on the lucid side automatically.
