How to make a sub counter in obs where the target number increases by one?

[dewto123]

I'm looking for a plugin that will allow me to add the number of follows/subscribers that count towards the goal. However, I want the goal counter to always be 1 greater than the number of current subscribers. Is there anything like that? I've searched on YouTube, TikTok, and the forum, but I couldn't find anything. Please help, because I know something like that exists, because I saw it from a streamer. Thank u all.
