Metadata title editting. How to?

Hi there.

I have recently swiched on New Look in PowerBI service and noticed that I had a typo in the title (and in fact an older version title).  I have search for how to change them, but I cant seem to find it.

What I want to change the Title that appears in the middle of the top pane "Land Slaes".  How and where do I update this?

 Thanks in advance.
