See #268450 (comment) for my verification that this PR only affects Command Palette visibility of this command. Please consider approving it.

[isidorn]

Thanks for trying it out. Having this in the command palette makes sense. I can also verify this once it hits the insiders build the day after

[gjsjohnmurray]

Thanks @isidorn. Please allow workflows to run, and set it to auto merge.

[gjsjohnmurray]

@isidorn please approve the workflows to run once more. I merged main into this branch as a way of getting the license/cla check to succeed (which it did), but now need other workflows approving.
