Email URL Error

Brave: 75.0.3770.100 (Official Build) (64-bit)
Mac OS Mojave

I’m not sure if this is a problem in Brave or in the extension (“Share link via email” by Cobote).

I’m getting this popup when I do an Email Link using the extension. It comes up every time, even after I check the box. The option in the extension is set to send with the default email client.

Mailto%3A%20Window

Is there a way to set the default email client in Brave when it gets a Mailto: in the URL bar?

Thanks.
