How can I get a list of all active personal access tokens?

I can generate a token with the command “cells admin user token”
But how do I get a list of tokens that were generated by (or for) a particular user?
I couldn’t find them in the main database (MariaDB/MySQL).

Token are stored in this table: idm_personal_tokens

Thanks.
I hadn’t noticed that they are stored as SHA256 strings.
