My educated guess says that you could find the variable parts (here c={longitude},{latitude}&z={zoom}) and therefore propose to use following values to go to the other websites):
template
value
{{longitude}}
2.31711259637669
{{latitude}}
48.84148703642347
{{zoom}}
11
That would raise farther acceptance for multiple layers portals.
I've added:
as proposed in https://wiki.openstreetmap.org/wiki/Talk:OSM_Smart_Menu#France. Then I changed the layers displayed by Géoportail (inside Géoportail): https://www.geoportail.gouv.fr/carte?c=2.31711259637669,48.84148703642347&z=11&l0=GEOGRAPHICALGRIDSYSTEMS.PLANIGNV2::GEOPORTAIL:OGC:WMTS(1)&permalink=yes

Don't worry, the tool is already a must have ;-).
