I use https://obs.camera/ https://obs.camera/ with my iPhone 11 for lessons with my music teacher and it works great. Paired with the virtual video out feature of OBS it’s really easy to use with zoom as well. Another option is https://www.elgato.com/en/epoccam https://www.elgato.com/en/epoccam but I haven’t used it much. Their software feels very janky compared to OBS Camera but I know it works (my teacher uses it in his end for our lessons)
