How to properly use Watchcat with Modem Manager?

I have set the mode to:
Restart Interface

Period:
5m

Host To Check:
8.8.8.8

Check Interval:
10s

Ping Packet Size:
56 bytes

Interface:
br-lan

Name of ModemManager Interface:
4g-modemmanger


Basically, I want it to check every 10s, if it can ping successfully, and restart the modem interface if the ping fails.

But I am not sure it is working properly.

I am used to this feature in ROOTer, where I had the settings below, but I want to replicate on Openwrt:

Connection Monitoring Status: Enabled with router reboot

Tracking Reliability 1
Ping Count 4
Ping interval 10 seconds
Ping timeout 2 seconds
Ping packet size in bytes 56
Interface down 3
Interface up 3
Tracking IP 8.8.8.8

Thanks.
