Power Step / Running Boards

Help!!! I have a 2019 Pearl White Nightshade with power steps. Driving down the highway I hit a ladder in the road and it broke a bracket that holds the step onto the power assembly. My step is hanging and has to be tied up. Went to Toyota and you have to purchase the entire assembly to get just the bracket. $1200+is the cost, OUCH. Anyone have any suggestions where to get just the bracket? Have tried off road part stores but they all say this step is a Toyota item and they are unable to get bracket. Any suggestions would be helpful.
Bracket in question is passenger side rear door.
Thanks in advance.

 

I wonder if you can help from this YouTuber if you send him a message on IG or FB about this. He had a parts buying video so I'm guessing he might have tips on this case. Again I'm not sure, just trying to help whatever way I can.
