Conditionally format the row header of a matrix chart

[carlalima]

How do I conditionally format the row header of a matrix chart in Power BI?

I have a matrix chart where:

In "Lines" I inserted the data from two columns of table 1. (Ex: Columns: A and B)

In "Columns" I inserted another column from table 1 (Ex: Column C) and a column from table 2 pulling the months (Ex: Column D).

In Values, insert the sum of two columns ( E and F ) from table 1.

I want to format all the lines, both the header lines and the value lines so that whenever the word "total" appears, the background color changes.

I was able to do this in the value fields by inserting a measure in the "conditional formatting" option using this DAX formula:
"Format 1 = IF(CONTAINSSTRING(SELECTEDVALUE(TABLE1[COLUMN A]), "TOTAL"), "#CCCCCC", BLANK())"

But I'm not able to format the line headers this way.

All the tutorials I see are related to column formatting, column headers and values...
