Conditional Formatting in Clustered Column Chart

Hello,

I am new to PowerBI and I am working on a report which fetches the Media Creation Time (highlighted in Green) and Media Validation Time (highlighted in Blue) in a single Clustered Column Chart as shown below.

I need to format the columns of Media Creation Time such that if Sum of Media Creation Time is more than 7 then the Column colour should be Red.

Please Note: The time is in 'Decimal Number' format so Number to Time conversion will not be an issue.

I do not know why I am not able to find Conditional Formatting option in Format pane.

Is there any way we can do the conditional formatting.
