Shorten or Remove Description for Events?

Hello again! You were so helpful in answering my first question, so I’m hoping you can help me with a second question. ??

I would like to shorten or remove the description for events (when you hover over the title in desktop mode, or when you click on the calendar date in mobile mode). It’s a lot of text, especially in mobile mode.

I’ve looked through the Knowledgebase but couldn’t find what I was looking for. Maybe I just didn’t know what to search for?

Thanks in advance for your support!
