How to remove noise from mouse sound?

I am Audacity beginner.
I am trying to edit the sound quality before the automatic transcription can be done by verifying the conference voice with a business order.
The sound source is an mp3 file recorded with an IC recorder.

The volume can be adjusted to some extent, but the sound of mouse clicks and key touch sounds
It sounds very much. I can’t get click noise and it’s not in the sample. How can I remove this sound?
I’m sure there are people who face the same problems, but I’m sorry.

There is a free de-click plugin for Audacity here …
but it’s only going to reduce mouse-clicks rather than remove them completely.

If the keyboard noises are louder than everything else, (e.g. recording via computer’s built in-mic),
try the pop-mute plugin …
