How do you see how much Karma a specific thread / community needs?

I'm new to posting here, but I've been a long time spectator. I recently decided to comment on few posts in the marketing channel specifically on Creative Strategy / Paid Socials and after writing a long message on a post it was removed by a bot. Now just to save some frustration, how can you tell how much Karma is required to answer and how can you tell how much you have already? I guess there are already conversations around how to earn more, but would also love to learn about that a bit more.
