Power BI edit interactions

Hi,
Can someone tell me how to do this, I have a matrix and pie chart and I don't want the chart to affect the matrix,
all the instructions I find say select the visual you don't want affected , go to format and 'edit interactions',

I have now found the anser, I was lookin in the wrong 'Format' it's the Format menu table , and the option is on the far left.
