Clicking Windows 10 Notification (Ads) opens Dissenter

Clicking Windows 10 Notification opens Dissenter.

Default browser is Brave.

It is what I write. Nothing more to add. Why is this happening?

@sickbattery,
Was Dissenter your previous default browser? Also, you browser default may be set to Brave, but in Windows System settings, you may have .html/ .htm links set to open in Dissenter.
