How to find records in Postgres that contain an object with a specific value?

Question

PostgreSQL

There is a record of this kind in the database:
{name: 'a', contacts: {emal: '[email protected]', number: '123124124'}
} whose email is equal to a certain value?
I went through foreign resources, but did not find anything. The documentation is the same too.

If there is such a strange format, then write its parser.
