Airpods 4 output issues

When I answer phone calls or am on video calls on my mac, the other person can't hear me talking or can only hear my background (e.g., noises, people talking in the background) and not her me talking (but can hear someone in the distance "talking loudly"), when using my airpods4. I can hear the other person without any issues, but they can't hear me. My airpods are connected and it's only when using my airpods and not other headphones.
