How to enable SPICE Guest tools on macOS Guest?

(macOS 15) Improved macOS guest support The last window size (including full screen size) will be restored when the guest supports dynamic resolution. Removable drives and shared directories can now be ejected and changed while the macOS VM is running. Copy/paste synchronization between macOS 15 guest and host now works when the guest tools are installed (from the CD icon in the toolbar).

I don't see an option to install it in the guest. I am on UTM 4.6.1 and using an IPSW file that I sourced from outside UTM.

Alright, so I manually installed utm-guest-tools-macos-0.22.1.img and added it a removable drive to my existing macOS guest VM. I then opened the GUEST TOOLS image and installed spice-vdagent-0.22.1.pkg but clipboard sharing between the macOS guest and the macOS host still did not work. Both the guests and the host are on macOS 15.1.1

Does the spice-vdagent-0.22.1.pkg need to be installed on the host too?
