you can buy BEACH on pancakeswap also, but you need BNB from binance or binance.us converted to BSC (via a binance chain wallet), then that gets sent to metamask.
They use BEACH. It comes up and you click on it. I used Uniswap, set the slippage to 15%. I prefer using ETH, although the fees are higher. You have to import and create the coin on Metamask as well to see your buy. I created the imported token on Metamask first by using the code at coinmarketcap.com. With the Uniswap and Metamask linked, I selected Beach and it came up as I had it on my Metamask showing 0 tokens in it.
