If a user clicks an action link from w/in a modal and is then taken to a separate page, do they return to that open modal after completing the action?

I'm designing an internal tool that enables my coworkers to curate post-op care plans for orthopedic patients on our platform (basically sending educational content to users at specific intervals).

I'm running into a challenge with one of the main flows, which is adding exercise videos to a care plans. Right now, on the main care plan page, you click an "Add Exercise" CTA that opens up a modal (shown here) where the user is able to multi-select the exercises to be added. Cool.

BUT a dictated requirement was that the user should also be able to create a totally new exercise from the same modal (see arrow). This makes sense in terms of supporting the user's workflow, but I'm stuck on the ensuing flow; like, I know that clicking "Create New Exercise" will flip the user over to the "Create New Exercise" page where they can build that content - but after the user creates the new exercise and clicks save, what does the user return to? Do they return to the original page with the still-open modal that now has a little "Exercise Created" confirmation message?

I honestly think this supports the user's goals best, but is it strange/bad ux that the user comes back to the original page and the original modal is still open? Am I missing another, better, interaction entirely?

Thanks everyone, eager to hear what you think!

should this modal stay open when the user returns from a separate page?
