Signing XCFrameworks with the Cloud Managed Distribution Certificate

According to the new requirements for binary XCFrameworks they should be code signed. I watched the WWDC23 video 10061-Verify app dependencies with digital signatures and while it helpfully provides the command to sign the framework after building, it doesn’t mention how to sign it when your distribution certificates are of the Cloud managed kind, and therefore not actually in the macOS Keychain.

My question is how can I sign a binary XCFramework when the only distribution certificate we have is in the cloud? I am a part of a team in App Store Connect, if that’s relevant.

Thanks 🙌
