MobileView doesn't appear to be working

[tuxgirl]

Hi!
I am pretty new to trilium, so this could be user error. I followed the instructions in the scripts to copy both scripts into JS frontend notes, and applied the label and the relationship to setupButton.js. When I tried to load the page in my mobile browser, I didn't see any new buttons, though. I think that could be related to the errors I'm seeing in the notes. In setupButton.js, on line 7 (async function setupButton() {", there's an error that says "Parsing error: unexpected token function", and in mobileView.js, it is giving me an error on line 7 for an unexpected character `.

I am guessing that those errors are why it won't run, but I'm not sure why it is giving the errors. Javascript isn't a language I use, but it doesn't appear to be noticeably wrong to me.

Any advice for what I could be doing wrong?
Thanks!

The setup button note should have the following relationship and label

~MobileViewWidget=Mobile View.js #run=frontendStartup

Both should be JS front end. Also which version of trilium are you using?
