Bonjour Myst,
My apologies for writing in English. Briefly: Please see phab:T172396 ("Tool "coord" loads assets from Google Maps") -- This needs to be resolved as soon as possible, because (A) it is loading third-party resources without user-consent, and (B) Google will be cutting off access soon anyway unless you have an API key, per phab:T196418
If you have questions, there are related tasks listed at phab:172659#4075691 which might help. Otherwise, you can ask for help on the cloud@lists.wikimedia.org mailing list or the #wikimedia-cloud Freenode IRC channel.
Much thanks.
