security warning when trying to install on mac os

[blockiindahood]

Hello together,
when trying to open the macOS Sillicon installer for version 1.9.24,I get the following message:

Translation: Apple could not verify that “Chataigne-osx-silicon-1.9.24.pkg™ is free of malware that could damage your Mac or violate your privacy.

Never got that before when installing chataigne. I am running macOS 15.1.
Just thought I report about this although you can skip this check in the settings of mac os.
