Error: Why don't I see an object "Virtual meeting room" in the ILIAS button "Add new object"?

Since the ILIAS object "Virtual meeting room" has not been available for a long time, it may not yet be displayed in courses that were created before the integration.

You will find step-by-step instructions in the ILIAS learning module in the section "Creating the Virtual Meeting Room plug-in in "old" ILIAS courses".
