What app views or converts windows outlook .msg files on Mac sequoia?

I recently switched my small business from windows to Mac. I found that the saved email messages from windows as .msg files cannot be opened. I learned this is a relatively old, known issue. I want to get an app that enables easy viewing of these emails (or perhaps converting them to .eml). Surprisingly, I am struggling to find current apps. It seems like app development in this field stopped in 2022-2023. Did a different answer supplant them? I understand that I can email the old .msg file to myself and open it with online outlook, but I want to avoid that hassle. Renaming it to .eml did not work.

Anyone using an app on macOS 15 to view/convert .msg files that they can recommend?

Thanks for your help!
