Wait step in a workflow

[Richard Williams (FCF)]

I have changed my PR Release WF to check that the PR is not blocked by a
user, if it is then the background release repeats.  I am using a 'loop
until' which works, however  I get an endless loop error if the PR is
blocked for too long.  I wish to add in a wait event of maybe  5 mins before
the release is tried again.  How do I go about this?
 
Thank you
