Hello my friend, click-and-dragged the file into the → brave://extensions page url and not was able to add the extension into the browser directly.
Now what I did was to change the crx extension to zip and unzip it to folder of the same name of the downloaded file with winrar -right click, then in developer choose the option load unzipped folder and the extension will be added in the browser, I tried it in brave similar to crome.
greetings to all from
