How does Intune know about custom macOS developer certificates

We (an organization) want to start with (re-)packaging of macOS applications and distribution with Intune. I am aware that I will need to sign a .pkg file with a Developer Certificate for distribution as an LOB-Application. **Question:** Do I (or the customer) need to install our developer certificate in Intune such that it knows the certificate for checking the package prior distribution or are all developer certificates of Apple are known to Intune? PS: If you have any official document which answers this question, I would also appreciate it.
