Align right menu items

Hi
I am using a side menu on desktops, and I have set the minimalistic one.
The thing is that by default, the menu items are aligned to the left and I can’t find the setting to align it to the right.

In the mobile menu I find the option to do that. However, in the minimalistic menu I can’t find it.

Also I tried to find the way to make it work with CSS and I couldn’t.

I would appreciate your help
