@FingerLeader

See the fifth line, add tc {"tc": "netem:{time:1000000} device:\"eth0\""} the device is still eth0 even I have specified the wlo1. This command could success iff you have eth0 device (however, I don't.)

I tested this command on CentOS7, but I don't have more information now (as it has been destroyed.)
