Include external link to organiser in calendar page

Hi all,

Is it possible to include the external link to the organiser of an event to the events in the calendar? On https://mirjamvanhengel.nl/calendar/, when you expand an item, the link ‘Zie hier voor meer informatie’ takes you to the single view of the event, where the external link to the organiser is visible. Is it possible to include this external URL already to the events on the calendar page (https://mirjamvanhengel.nl/calendar/) ?
I have no problem adjusting the code or twig files, but I was not able to find this.

Thanks in advance!
Ben
