A Humbling Moment at Maghrib Prayer

Asalam alaykum, brothers and sisters. I wanted to share something that happened this week that left me feeling a bit embarrassed. I had the chance to lead the Maghrib prayer at my local mosque. Since Arabic isn't my first or second language, I sometimes struggle with pronunciation, but I try my best. That day, the mosque was quiet when the adhan went off, and since no one else was around, I gave the adhan myself. Alhamdulillah, that went okay. Then, when it was time for the prayer, I made the iqamah. I turned and gestured toward the microphone, hoping someone might come forward to lead, but no one did, so I took on the role. I thought I did alright, though I'm sure my non-native Arabic was noticeable. After finishing the prayer, I faced the congregation for dhikr and performed my two sunnah prayers. As I was leaving, a brother approached me and kindly explained that typically, the person with the most Quranic knowledge, native Arabic fluency, or the eldest should lead. He mentioned I'd made some pronunciation errors and suggested next time I let someone else, like him-a native speaker-lead instead. He said he'd arrived after the prayer started, otherwise he would have stepped up. Honestly, it hit me hard. I was so excited to lead, but after his words, I felt really embarrassed. I almost stayed for the last prayer but ended up going home out of shyness. If he noticed mistakes, others might have too, and now I'm feeling nervous about returning to the mosque. Any advice on how to handle this would be deeply appreciated-what would you do in this situation?
