How to view created MySQL links?

Question

MySQL

Good day! I can not find a command on the Internet to display already created links. Just because I did not manually indicate the name of the connection, I do not know what it is called. phpMyAdmin shows the name of this link, but I would like to know how to do it in the console.

The first result from Google is quite working:

SELECT
  `TABLE_SCHEMA`
  `TABLE_NAME`,
  `COLUMN_NAME`,
  `REFERENCED_TABLE_SCHEMA`, 
  `REFERENCED_TABLE_NAME`,
  `REFERENCED_COLUMN_NAME`
FROM
  `INFORMATION_SCHEMA`.`KEY_COLUMN_USAGE`
WHERE
  `REFERENCED_TABLE_NAME` IS NOT NULL;
