docs: def getactivitiesurl(dummyId='', *args, **kwargs):
      """Request Activities URL.
  
      dummyId is used because MambuStruct always requires an Id from an
      entity, but the Mambu API doesn't requires it for Activities,
      because of that dummyId defaults to '', but in practice it is never
      used (if someone sends dummyId='someId' nothing happens). The fact
      of forcing to send an entid is a technical debt that should be
      payed.
  
      Currently implemented filter parameters:
      * from
      * to
      * branchID
      * clientID
      * centreID
      * userID
      * loanAccountID
      * groupID
      * limit
  
      See Mambu official developer documentation for further details, and
      info on parameters that may be implemented here in the future.
