To set will delay interval

I trying to test will delay interval property in MQTT 5. so can you help me how to set will dealy interval in mosquitto.conf file. currently i set notification topic as my will topic.

I’m afraid It’s not currently possible to set a will delay interval for bridge will topics, if that’s what you mean.



If not possible then why in MQTT 5 this new property introduces to set will delay interval and what is the solution of it.
