Anchor spl_token Metadata

Hi, I am currently developing SmartContract through Anchor

I have a question about spl_token in Anchor, so leave a comment

I checked that if making a token through spl-token cli, it is usually marked as Token in sol scan

In the case of ERC20, only essential functions is defined,
it is recognized as Token in scan,

but I wonder how it is recognized as Token in anchor

this is my anchor Program : Solscan

but I want like this

Is there a site I can refer to in this case?

thank you for all comment.
