Trying to install blendos alongside other linux installs. Doesn't show up in boot menu

This is on a uefi system. I do manual partitioning and select fat32 drive with 1g for Boot and a 100gb brtfs partition for System.

I have Fedora, Endeavour and PopOS installed on the same drive in different partitions and they all show up in the boot menu and boot just fine. Blendos doesn't show up. I've reinstalled several times and nothing.
