I have a recording with two speakers where only one of the speakers has an echo. The enhance feature didn't do anything to resolve the echo. Is there anything I can do about this?

The video is actually a screen record, and I selected both mic and internal computer inputs for the audio portion of the recording, hence why the audio for the person on the other end was duplicated. I thought the program would recognize this as an echo and consolidate them, but when I ran it through “enhance”, it did nothing for the other person’s audio, so the echo is still there. Does anyone know what I can do to fix this?
