Quarantine
macOS displays a dialog containing this error and the options "Move to Bin" and "Cancel" when launching unsigned applications for the first time:
"* cannot be opened because the developer cannot be verified"
To allow list via the CLI:
xattr -r -d com.apple.quarantine "$(which session-manager-plugin)"
Else, locate the app or binary in Finder:
open -R "$(which session-manager-plugin)"
Then right-click it and select Open.
