Help pleaseh

I currently live in MA and was on-the-job trained with no schooling and very little guidance from office management. I got my DANB RHS certification and my DA license in 2019. I am moving to CT and per state requirements, just got my DANB ICE certification. Herein lies my question: I stumbled upon the “Renew” tab on the DANB website when searching for study outlines for the IC exam. The information on DANB website does not specify which certification it is referring to and the closest straight answer I can find on the website refers to “DANB Certified Dental Assistants” which means what? Those that have taken the CDA exam? Or dental assistants with any DANB certification they offer? Has my RHS been void since 2020 because I didn’t know I had to renew it? Not one other person in my office knows and I am not the only one with DANB certs, nor can we find a straight answer.
