Access tabs directly via URL?

Hi !

I have followed the description as seen here : https://yikesplugins.com/support/knowledge-base/how-can-i-access-my-tabs-directly-via-url/

I cant seem to find out where and how to change to title of my own custom tab (ie “Test”) and where to find, locate and add link to designated text which i would like to link for.

ie : I have a piece of text on productpage, which i would like to link to custom tab+content with auto jumd down and opening when clicking on this piece of text.

Added code to snippets as well to functions.php, but just adding code and make “my custom tab” does not result in showing anything.

Using latest version of WP+Woo and flatsome theme.

What am i doing wrong?

thanks!
