Importing keyboard shortcuts from MuseScore 3 to MuseScore 4

I just downloaded MuseScore 4, and I'm finding that some of the keyboard shortcuts from MuseScore 3 don't work. I was thinking maybe I could just import my keyboard shortcuts from version three, but I'm not sure how to do that or if it's even possible. In MuseScore three, in the preferences, there is a import and an export tab, but I'm not sure how to proceed.
In the shortcuts tab there is save and a load button, but again, I am in doubt.
Would appreciate any advice.
