remove clicks from an existing track

Mac 10.14, Audacity 2.1.1
I have an existing audio recording and I don’t like some sharp sounds in it. It’s a voice talking. The sounds may be called clicks. I have removed the worst just by cutting them out, but then I tried to reduce the general sharpness by using the filters, but I wasn’t successful. Can someone give me an idea how to solve this problem?

Could you post a picture of the waveform where the clicks occur? Zoom in so you can see the waves.
