How can I add the Text Highlight Color control to a custom xml ribbon in PowerPoint?

Question

I'm building a custom ribbon in PowerPoint and would like to include the Text Highlight Color Picker control on it. I've found an idMso called TextHighlightColorPicker, but it's not recognised by PowerPoint so I just get an error when I open it.

<control idMso="TextHighlightColorPicker" size="large" label=" " />

I've tried various other idMso with the word 'highlight' in but to no avail. I imagine it's simply not available for custom ribbons, but I thought I check to see if anyone knows, because it's seems strange that most of the other buttons are available but not that one.

Thanks in advance!

I eventually found the idMso as per the instructions in Eugene Astafiev's answer, it turns out it is only avaiable in subscription versions. The id is "TextHighlightColorPickerLicense".
