Users - Enterprise Login Button looks odd

I feel like the "Enterprise Login" button in the Add User dialog looks odd.

I think a toggle switch would provide a better UX, but then it would look odd being at the bottom of the dialog

Maybe another solution would be to move the "Enterprise Login" button inside the Toggle Buttons group on the top, with "Standard" and Administrator (?)

I don't have any other idea but I think that as of now it doesn't feel quite right
