[OTRS ITSM] How to delete a change from user interface

[shomotrs]

Hello,

Using OTRS 3.1.7 with ITSM module. I am currently testing the change module with change manager rights.
When we zoom on a workorder there is a "delete" button to delete it. But there is no "delete" button when we zoom on a change.
I tried to configure some parameters like:
ITSM Change Management -> Frontend::Agent::ViewChangeDelete

and also in: ITSM Change Management -> Frontend::Agent::ModuleRegistration, I activated the parameter: Frontend::Module###AgentITSMChangeDelete
But no "delete" button when we zoom on a change. Did I miss some parameters ?

I tried to apply the same parameters as for the workorders to make the "delete" button appear but it does not work so far.

I know it is possible to use the ITSMChangeDelete.pl procedure but because of internal security policy in our organization I don't have the rights to execute it.

Some help would be appreciated !
Regards.
