Zoom proposes an Outlook agenda (which I do not use) in stead of Mac agenda

[GuyDeVl]

When scheduling a Zoom meeting on my Mac, Zoom proposes to set the meeting into an Outlook agenda (which I do not use). This is new since I have my new Mac. On my old Mac, Zoom always proposed an iCal (Mac) format agenda. I suppose I need to set this somewhere but where ?
Can anybody help me ?

Cheers,

Guy
