How to improve the sound.. Clattering and whistling peaks

Audio recording of the conversation. The quality is generally not bad, but on the hissing sounds there are loud whistling noises hitting the ears. What tool can be used to smooth out this defect?

Win11/Audacity 3.2.0

Moderator note: no need to Shout - I reduced the type-size to normal.
The Forum Elves don’t pay more attention if the text is bigger, rather it just annoys them.

A de-esser. There is an Audacity-specific de-esser plugin called desibilator.
[ Other free de-esser plugins are available, but which work in real-time, e.g. … ]

Desibilator works great! I downloaded it, threw it into plug-ins, opened in effects and applied it without changing any settings. I immediately got an excellent result, all the sharp hissing sounds that hit my ears are gone, now you can listen to the recording normally. Thanks a lot!!!
