For me, the ideal would be to put it in the event preview
For me, this has two advantages
- it avoids having to click on the event to see the description, allowing people to see if the event in question is interesting or not
- same case for adding to the personal calendar. Seeing the description beforehand helps me decide whether or not to add it to my calendar, avoiding too many manipulations
Be careful, this is just an idea. It’s sometimes easier said than coded
