Randomise CMS item selection on click

Hi All,

Hoping you can help with a pernickety solve thats been duping me for a week. Looked around forums and a lot of similar solutions but nothing similar to my needs:

I have a modal which displays on click with a randomised piece of content from a collection item (A zen mantra) appearing on it. At the moment (thanks to this: Showing a random featured CMS item in Webflow | Tutorial - YouTube) it randomises with every page refresh.

I’m looking to make it randomise on every click! I’ve tried adapting the JQuery myself but to no avail. (I’m very beginner)

It’s at the very bottom of the page – the green hanging tags on the trees are the trigger in the zen garden.

Any hints or tips greatly appreciated.
