Install the os-prober package, and then run update-grub (as root) if the os-prober postinst script didn't already do it for you. Also note that if you upgrade to Debian 12 at some point, just having os-prober installed won't be enough. You'll also have to *enable* it. See <https://www.debian.org/releases/bookworm/amd64/release-notes/ch-information.en.html#grub-os-prober>.
