You've created the list that will contain all the specific fields from this web part.
Open the list that you have created, and copy the list URL, you will need it to connect the list to the web part.
If you want to give a name to your Quick Links, here is the place where you can define it.
In this field, you need to paste the list URL that you copied when you finished creating the list.
It is recommended that you use relative paths in this field.. So instead of using an URL like https://company.sharepoint.com/sites/Home/Lists/Links, you should use something like /sites/Home/Lists/Links. This will ensure that the web part will work regardless of how you’re accessing the site.
