They did, actually. That was their primary tactic, to disrupt, fade away, and reappear. They copied it from their sympathizers in Hong Kong (didn't work too well for HKers either, btw). The type of street conflicts so many are now calling for will require long term occupation and control of territory--as the red shirts did in 2010. Personally, I doubt that is possible. More of their hit and run strategy to be sure. But that will fade away. After all, it faded away in 2021, didn't it?
