Hi,
There are not out of the box functionality for a delay as you are requesting. There is a customer assertion called Delay Assertion and here is the description for it.
The delay assertion is a very simple assertion that effectively causes the execution of the policy to sleep for a given time. The assertion can be useful in testing and development whenever some latency needs to be simulated. This assertion is not intended for production usage.
If this is something you are looking for, please open a support issue so the support engineer can get you an approval to use the assertion
Hope this helps
Thanks
Abs
