How to get idMso Ribbonname of a selected meeting in outlook calendar?

how can i reference this ribbon (idMso) to display my custom add in group there? The ribbon is only visible when I select an appointment item. I want to get the item from the selection with my add in. But I don't know the idMso of this ribbon. It is not TabMeeting or TabCalender.

    <?xml version="1.0" encoding="UTF-8"?>
<customUI xmlns="" onLoad="Ribbon_Load">
  <ribbon startFromScratch="0">
      <!--<tab idMso="TabAddIns" insertBeforeMso="TabMail">-->
      <tab idMso="TabMeeting">
        <group id="GetTermine"
           <toggleButton id="OnActionCallback" label="Get Termine" size="large" onAction="OnActionCallback" />
        <tab idMso="TabAppointment">
            <group id="GetTermine1"
                <toggleButton id="OnActionCallback1" label="Get Termine" size="large" onAction="OnActionCallback" />
