Configure a Gatekeeper setting in Apple Business Essentials
macOS includes a technology called Gatekeeper, which is designed to help ensure that, by default, only trusted software runs on a user’s Mac. Trusted software refers to apps that have been signed by the App Store or signed by a registered developer and notarized by Apple. Both the App Store review process and the notarization pipeline are designed to ensure that apps contain no known malware. Sometimes using even a benign app triggers the loading of a malicious plug-in without the user’s knowledge. Gatekeeper protects against the distribution of these malicious plug-ins. Sometimes plug-ins are automatically loaded alongside an app. To avoid loading a possibly malicious plug-in, Gatekeeper opens those apps from randomized, read-only locations.
In Apple Business Essentials, sign in with a user that has the role of Administrator.

Choose whether to allow a user to use the contextual menu in the Finder to open an app that Gatekeeper would prevent.
