Grub not showing/ discovering Win10

Ok, so problem is as described in subject: grub doesn't seem to know about win10 installation. It's a brand new hard drive and I decided to just do fresh installs of bot Ubuntu and win10. Due to install failure on Ubuntu when trying to install Windows first, I decided to wipe the disk and install Ubuntu first. Clean install. Then I made an NTFS partition and ran the windows installer, instructing it to install to the NTFS partition. Successful install. However, grub only offers options for Ubuntu. Tried update-grub and the grub customizer, although I'm not really sure what to put in the script block. I tried to copy paste a couple thing s I googled, but they didn't work. Windows boots fine if I choose the correct option in BIOS/UEFI, but I'd like to be able to choose it from grub. Here's screenshots of the Windows disk manager, Ubuntu disks, and lsblk. Couldn't find anything helpful on google so hopefully someone knows how to fix.
