Should I Tell Him About My Past Nose Surgery Before Marriage?

Assalamu alaikum, dear sisters. I’m in need of some sincere advice. Five years ago, when I was 18, I had a small rhinoplasty to refine the tip of my nose. I did it secretly because I was really struggling with how I looked and my iman was at a low point. Alhamdulillah, no one ever noticed the change, but deep down I’ve always carried regret. Since then, I’ve returned to my deen and made tawbah sincerely-I truly wish I hadn’t done it, as it wasn’t worth the sin. Now, I’m talking to a practicing brother for marriage, with my brother involved in our conversations. He’s a good man, masha’Allah, and I feel this could be serious. My heart says I shouldn’t hide anything, but I’m unsure if this minor thing from my past needs to be shared. It was so long ago, and I’ve repented. Is it obligatory to tell him? If not, would you still advise me to be open about it? I want to start a marriage with barakah and no secrets, but I’m scared of causing unnecessary issues. Jazakum Allahu khayran for any guidance.
