Modal question slash Pomodoro Clock

My Pomodoro Clock

I could use some advice if anyone is familiar with materialize/modals. I got the modal to open on page load but I can’t get the button/a to link to it. I am doing everything the docs say to do and have seen a codepen with the same code as I have. The only thing I can think of is due to my button being in a “floating action button” set maybe it doesnt work? Also, any thoughts on the way the page functions would be appreciated. Thanks.
