Request Chain Timeout Issue

I am Chaining multiple requests together but the last request does not execute due to the long wait

I have
Request A, - Response needed for a field in the request body of B
Request B, - Main Request
Request C, - Response needed to Verify data saved from B

Request B is the main request and I am sending both A and C via callback function and I am using setTimeout to delay the execution of Request C in post processor custom script

the problem is that the run finishes without executing Request C if i set too long of a delay I need 6 mins delay to ensure that I get the proper response but it seems that the limit of a run is more or less 3 mins only

I have it setup this way because I prefer fetching the data I need for verification locally instead of assigning everything on environment variables

How do I make it so that I set a 6 min delay before executing a function on post response?

You can try it.
