Looking for a microphone boom arm, but how do they work?

This is a most excellent place for technology news and articles.
Mic arms will have a tripod style screw mount at the end and then will probably come with several different pieces that can fit on the end. The one you're describing is a shock mount and they should list the microphone diameters they accept. You'll probably also be able to directly mount the microphone or use a rigid clip.
I bought this one a few years ago to use with my Samson Q2U: https://www.amazon.com/gp/product/B07X1ZWS2H The shock mount doesn't fit that microphone but the clip mount does.
