How do I play a Chess960 bot?

I decided to try chess960, and 2 days ago I played a chess960 bot on chess.com. I wanted to play a bot again, but I cannot figure out how to do it again. If I go to the game I played and click rematch, I get a standard game. I can't recreate the convoluted path I took to create the original game, although I did manage to create a 960 game and select the bot from a list. A board appeared, but the bot never made a move (was white). The bot had changed her name from the usual Wendy to Wendy-bot. I suspect she was assimilated by the chess AI cartel.

Found it again. Microsoft must advise on UI design. Anyow, you select a bot, the click the arrowhead by the gold crowns in the lower left. You can then select Custom and chess960.
