Break-out room not found in setting

I am the owner of a Pro account since 2023. I had no need to use break-out rooms before. Now that my work requires break-out rooms I cannot find that feature. I’ve tried on my laptop and phone to no avail. I have email support, read articles, chatbot but no success. I have followed all the steps given by chatbot and the article that is: login into my account, go to the left had panel; click account management, click advance, click meetings there no such feature as break-out room under meeting to enable. what could be the problem?
