On the SEC, you will see an address that is provided there, which is the token contract address. You can copy the address and scan it in whatever chain the token is under.

The total supply is 420,000,000 SEC.
Note: The token has very little liquidity and was just created about 18 hours ago; I don't really see it as a good choice of investment. Do your own research before you make any form of purchase on that token in order not to get your money stockpiled somewhere.
