Failing to install Extension in Brave

Hello,

Trying to install the browser extension in Brave. I've been to the Chrome Web store to install. There I get a
"Install in Brave" button, but when I click, download, and the download "ends", I get the following messages:

I added Brave with Full Disk Access (thinking it might be a permissions error on the Download Folder, but no luck!

Any idea how to fix this (or Download the extension so I can try to install it manually?

Thanks!
