To have Google Calendar Location links point to other Map application?
You can try an of the following to open the links in other gps applications (Here Wego in this case);


Editing links opened by default with Google Maps


To adjust this behaviour, go to Settings ➡ Apps ➡ Maps ➡ Open by default ➡Open supported links ➡ Here you can select the appropriate choice e.g (Ask every time)



In this way location links are not automatically opened by Maps app rather you can select the one you wish to use e.g Here WeGo

(Note remember to clear the defaults first)


Using Send to GPS app



  With this application you can send your position, or any other POI,
  using Google maps to your GPS program


This in turn allows once to open the links directly from the target application. Although not listed some users have be reported its compatibility with Here WeGo.
