I have a thunderforest background map for my project for which I had not given an API key. I now want to publish some maps and need to add the key to remove the overlay.
The problem is that I can't figure out how to change the urls for the layers. I think I loaded it originally from the data manager => XYZ Tile menus (this matches what I found searching) but in the current version of QGIS that option is not listed.
I assume I could hack the project file and add the key to the url there but I would rather do this properly!
