That's one option. You can also use the MFA flow to invoke Password, and have a button there signaling a custom event that you script a transition off of.

You could also use the older feature in the Password flow to invoke the other flow as an "extended" flow, but my advice would be to avoid that, it's more confusing to set up than the MFA options and it's a feature that's possibly going to end up deprecated.
