Can the tools in the floating ('quick actions') toolbar be customized?

Hi All,

As the title says, I am wondering if the tools that are shown in the floating toolbar--referred to as the 'quick actions' toolbar in the settings--can be customized? I cannot seem to find any way to do so.

What I would like is to add the "change color" tool to the floating toolbar when a highlight is selected, though in general I would like to have more options.

This webpage (https://helpx.adobe.com/au/acrobat/using/commenting-pdfs.html)--which claims to apply to Acrobat 2020 and DC--hows that the change color tool already exists in this toolbar, but I am trialing Arcobat Pro 2020 and in the attached image you can see that it does not exist.

Thoughts?

Thank you in advance for your time.

Tony
