How do you customize the global bar?

I want to add other tools such as "organize pages" to the global bar where E-Sign and Convert can be found. How do I do that in the new Acrobat layout?

Do you mean this bar:

Click the 3 points at the end of the bar.

or this bar:

Click and hold the icons to move them around.
