How to install Guest Additions for AlmaLinux-10.2-aarch64-minimal inside VirtualBox on a MacBook Air (M5)?

I have inserted Guest Additions. I have installed needed packages such as kernel-headers perl etc etc. I have created a folder and tried to run:

sudo mount /dev/sr0 /mnt/cdrom

I then try to cd into the folder and

sudo ./VBoxLinuxAdditions.run

When I get

Detected unsupported arm64 machine type.

So I try to run the VBoxLinuxAdditions-arm64.run which I have in the cdrom folder, among other such files. Then I get:

Verifying archive integrity...  100%   MD5 checksums are OK. All good.
