Too many Brave's browser's linked to Uphold

I just tried to install Brave nightly on my Mac and link it to Uphold. But I was told that I have too many linked browsers. I may have linked some Brave browsers on Linux VM’s that I no longer have. So how do I delete those other browsers that I no longer have or use so that I can link Brave Nightly on my Mac?
