I think this is a bit of a grey area tbh and if you did have an accident you could find yourself in a lengthy and possibly pointless battle. Just be patient and leave your
where it should be and keep it nice ready for when your all fixed again.
In my view your probably still insured but the doctors wouldn't want you driving as it could make your arm take longer to heal or you could run the risk or causing long term damage before it heals.
My advice personally though would be not to drive!!!
