Clickable link in location

Hello, first of all, great plugin, exactly what I was looking for. Just one tiny thing – I use the location field in the Google Calendar to add a link (usually to an Facebook Event) to be shown below the event title (see my use case: https://corispezzati.cz9.cz/spherae-sonantes/bude/), but I would like it to be clickable, that is to add to it the <a> tag with the href attribute equaling the string of the location field (I hope I explained it well enough, I really don’t know much about html). Could you help, or is there perhaps a workaround?

Edit: I see this might be possible with hooks, but I can’t wrap my head around it (that is, even to set them up…), any help greatly appreciated!
