RingCentral app - schedule a meeting - default meeting calendar

When scheduling a RingCentral video meeting, the RC app defaults to "Outlook web calendar" which we are not using at our company. Employees have to keep changing back to "Calendar app" every time there's an update to the RC app. We need a way to default the calendar option for users so that they don't have to keep switching this setting back. Another option might be to set the default to the "Calendar app".
