Project url to import from gitlab

Sorry stupid question but

I’m told for importing to github to look for the project url e.g.

However I don 't see this button

So am I suppose to clone the project?
Also if so do pulls using github desktop automatically pull to the main branch in gitlab, or do I need to pull in gitlab as well.

Or am I just suppose to use the url at the top of the page.
Sorry first time using git.
