It sucks for you indeed that you cant try out the bot properly, but you should still be able to test it somehow what.
I dont know if this only goes for me, but the bot cant currently auto join a new game, but it can still play the matches for you.
Just make the game windowed mode, drag it into one of the sides of your screen, open the bot, and place the bot so that the "start/stop" button is just above the game window. Then when the game is over press "Stop" start a new game and press "start". The only two things the bot dosent do this way is auto join a new match, and count the time the bot has been active.
