Vendor Information In Smarty Html Block

I'm new to CS Cart, I'm starting to get acquainted with the Smarty Block. and I come to ask for your help.
I would like to show the vendor information in a small block:
Vendor's Name
Vendor's address
Vendor's phone
Vendor's email
For now I have only managed to show the name of the seller but I don't know how to show the other information:

{$ company_id | fn_get_company_name}

Please could you tell me how should I add the other two variables?
Thank you very much
