How to perform a drill down?

[JBeyers]

According to this source, the drill-down feature is back in the web version of PowerBI. 
Now I'm struggling to find how the drill-down can be performed, I looked for examples of how the previous drill down could be performed. But I couldn't find the arrow icon. 

So how can I do this?

Already found the answer, I simply did not add the time functions on the X-axis
