How to use UVS to change the playback speed of the timeline?

Hello everyone, I know that in the timeline, I can use the PlayableDirector node’s pause function to pause, but I’m not sure which node to use to set its playback speed to 0. As shown in the image, I’ve found this separate setting node, but I don’t know which interface to connect it to. I’ve tried many nodes without success. Can anyone who understands this help me out?
