Install MS Office to Admin or Standard user account?

I have an Admin user account and a Standard user account. The standard account is the one I actually log into and use daily. The admin account is only for admin.

Which user should I be logged in as when I install MS Office 2019?

My concern is that if I install it to the admin account it might not be available on the standard account (or possibly use up the single license). Or that installing to the standard account is not the correct way to do it.
