Change hovertext fields of a treemap in plotly express

BTW, how can I insert more variables on hovertemplate?

I mean, I have tried to use a dataframe column with %{df.type}, but it renders literally %{df.type} instead of the value of such column for a given treemap cell

from documentation:

Template string used for rendering the information that appear on hover box. Note that this will override hoverinfo. Variables are inserted using %{variable}
Anything contained in tag <extra> is displayed in the secondary box, for example β€œ{fullData.name}”

thanks in advance!
