Modifying a sunburst chart with % symbols and joint legend

Question

I copied a code from this post to make a sunburst chart, but I need to make 2 modifications that I haven't been able to work out:

is to add % into the text, and
is to create a joined legend for both pies in the figure.

When I tried to insert \% after the number in the following for example (\% is in bold)

\arctext[N1][firstgreen][15pt](1.5)(90)(-3.6){|\footnotesize\bf\color{white}| 1 26 **\%**};

the whole thing crashed.

If anybody could point out how I can make these 2 modifications that'd be super helpful.

Macros need to be inside additional braces and surrounded by text (blanks will do}. text={ {\%} } — John Kormylo, Feb 19 '20 at 15:15
What sort of legend? See https://tex.stackexchange.com/questions/54794/using-a-pgfplots-style-legend-in-a-plain-old-tikzpicture/148855?r=SearchResults&s=4|31.1059#148855 — John Kormylo, Feb 19 '20 at 15:17

The wheelchart package, which I wrote, can be used.

The text in the arcs is given to the key arc data. The direction of this text depends on the angle of the middle of the arc given by \WCmidangle which is used in the key arc data dir. The position of this text is determined by the key arc data pos.

The gaps between the slices are obtained with the key gap.

The legend is determined by the key legend. This is a tabular which is placed in a \node. The rows are determined by the key legend row. The result of all rows can be obtained with \WClegend.
