You are not allowed to open program. Trying to open a home made program on mac osX (11.6) Big Sur

Hi.

We have made a program to manage wifi networks during student tests. We have then used the custom package making program Platypus 5.3 to make a installation package for this program where there is a script that copies some configuration files and finaly the app itself unto the application folder in OsX.

But when we try to run the installation package there is an error message in OsX saying you are not allowed to run the program "Install NetMonitor", contact the owner of the machine or an administrator for help.

How do you allow own programs to run on osX 11.6 Big Sur?

The usual way of entering security and then click "run this program anyway" doesn't appear as an option.

We have tried to allow the program file access in the Privacy windows under security and privacy in settings, without any luck.
