Brave Publishers & Rewards: is there a one-click button (JavaScript) method I can use to access the Brave's built in wallet

I usually run my web3 application via Chrome + the MetaMask extension, but started to test some of my applications through Brave. However, one of the things I’ve struggled with is replacing the MetaMask extension (which I use in Chrome) with Brave’s built in version of their crypto wallet. That said, is there a one-click method I can use to access the Brave’s built in wallet? Or do I need to use MetaMask and use the BAT in my MetaMask wallet?

I just want to be able to embed some JavaScript in my web page that will automatically launch “Brave Rewards” as if I clicked on the built-in “Brave Rewards” button, next to “Brave Shields.”
