Screenflow 10 not recording iMac screen

Hi, I have a new 2021 24'' Mac with Monterey and Screenflow 10.05. The problem is I cannot set Screenflow to record my computer's screen. I have given Screenflow permission to do so (by going into 'privacy' settings through 'system preferences' and clicking the box to allow 'Screenflow helper' to record the screen) On the Screenflow interface, I still cannot gain access to allow screen recording. Can you help? Thanks
