Currently, some of our editors accept EJSON (Insert/Edit in CRUD), while some accept Shell syntax (e.g. Agg pipeline builder). We do not display information about which editor accepts which kind of input.

I think we can and should add a toggle to the Editor component that allows switching between the two modes while editing (in the UI, this could look similar to what we’re working out for code formatting in COMPASS-5853), so that the ambiguity is resolved without requiring users to update their workflows.
