How to increase message execution timeout in python ServiceBusTrigger in Azure function

I am using python ServiceBusTrigger in Azure function and for every message received, it takes more than 5 minutes to process.
It seems default timeout for message execution in ServiceBusTrigger is 5 min, after that it is replaying message again for execution.

I want to increase timeout for execution time, such that message execution can run for longer time.

I have tried increasing functionTimeoutbelow setting in host.json, but still 5 min expiry is happening:
"extensionBundle": {
"id": "Microsoft.Azure.Functions.ExtensionBundle",
"version": "[2.*, 3.0.0)"
},
"functionTimeout":"00:30:00"

function logs for replaying of messages after 5 minutes:

But still i could see messages are re-executed in function after 5 mins, if execution is not completed within 5 mins.

    @Singh, Satyam ,

    For functions on consumption plan, the maximum timeout value that can be set is 10 minutes. For Dedicated and Premium plans, you can set to 30 minutes or more.

    Please try to increase the maxAutoRenewDuration value and match it with the function timeout value. According to the below github issue, it appears that the maxAutoRenewDuration can be set more than 5 minutes

    I hope this helps!
