Minecraft Migration Question

So today I migrated my Minecraft account. I realized I am still on an old Minecraft launcher and now I can't choose the Microsoft option. Now I realized I can't play Minecraft as if I don't have the Microsoft option and the old Minecraft launcher doesn't even have the Microsoft option. Can you please fix all of the old Minecraft launchers and give it an option to press Microsoft option? I am also using a Macbook Air. And I am using the 2.1.1350 launcher.
