How to invite counselor as recommender

Hello,

I need one letter of recommendation (for Early Decision) and I intend to get it from my counselor. I’ve already added her as a counselor. How do I assign her my recommendation within the Common App? Do I need to invite her again as a recommender this time and then assign the recommendation to her? Do I invite her again and then mark her as a teacher?

I’m very confused about this process and would appreciate some guidance!

Thank you!
