You can set up activities that are available only to subscribers of the VK group. To check if a person is a subscriber, select "Terms" - "VKontakte Terms" - "Check Subscription" in the left menu of the script
After creating a block and opening it, you can select the desired VK group from among the connected script channels and set up two ways for the bot to proceed further.
