Using QCMDEXC to call QEZSNDMG via DB2 stored procedure

Using QCMDEXC to call QEZSNDMG via DB2 stored procedure
Working on a side project where I use a set of views to identify contention of records within an iSeries set of physical files.
What I would like to do once identified is pull the user profile locking the record, and then send a break message to their terminal as an informational break message.
What I have found is the QEZSNDMG API. Simple enough to use interactively, but I'm trying to put together a command that would be used in conjunction with QCMDEXC API to issue the call to QEZSNDMG and alert the user that they are locking a record.
Reviewing the IBM documentation of the QEZSNDMG API, I see that there are two sets of option parameters, but nothing as required (which seems odd to me, but another topic for another day). But I continue to receive the error "Parameters passed on CALL do not match those required."
Here are some examples that I have tried from the command line so far:
Note: I would like to avoid using a CL or RPG program if possible but understand it may come to that using one of many examples I found before posting. Just want to exhaust this option before going down that road.
