If it’s a new bot then you need to contact your CSM or firstname.lastname@example.org where we will activate the searching and generating of prospects for the first time.
If the bot already is active and you still can't see any prospects then the bot's targeting might be too narrow. If so, the bot might have difficulties finding more prospects based on the current targeting.
A suggestion here is to widen your targeting by adding a few parameters. If you need help then you are welcome to contact your CSM or email@example.com.
