How do I install VirtualBox Guest Additions when running Silverblue as a guest?

I get read only filesystem, which is completely expected, but I don’t know how I would go about installing VirtualBox Guest Additions.

The read only filesystem is when trying to install via the inserted ISO image. When trying to install with rpm-ostree, it looks like it is already installed, but it definitely doesn’t seem to be working with things like dynamically updating the resolution on window resize.

$ sudo rpm-ostree install virtualbox-guest-additions
error: "virtualbox-guest-additions" is already provided by: virtualbox-guest-additions-6.0.4-2.fc30.x86_64. Use --allow-inactive to explicitly require it.

i am interested in that possiblity too as it would be very useful the same augmentations in the VM silverblue OS integrating with the host.

Try to set resolution via Gnome Settings (Settings->Devices->Displays->Resolution). Once I set my resolution this way, it has persisted across reboots. Now the resizes (Host+C, Host+L, Host+F) are working as intended.
