Purchased Windows 10 but Minecraft Launcher only shows Java or Minecraft Dungeons to purchase

Purchased Windows 10 but Minecraft Launcher only shows Java or Minecraft Dungeons to purchase.  My Microsoft/MoJang account previously had purchased Java Edition on one computer.  I want to install (and purchased for $50) Windows 10.  After doing the Minecraft install, Launcher does not show the Windows 10 option.  have tried to access Minecraft Windows 10 in other ways and contacted Microsoft support who suggested I contact MoJang support.
