Where I can change the title of the category navigation?

Hi,

I was successfully, to get a connection after a lot of trys.

But now, I have a new question.
I will show the categories from the shop like your demo theme, too.
As left big dropdown before the main menu.

but I dont find the position to change the title “Browse Categories”
I only find to change the “block” Icon before the text.

Where I can change the title of the category navigation?

Thank you.
