Extract user name from database

i have an HA instance with mariadb ad I need to extract some statistic based from users, for example all action done from an user in a day, now with a SQL query I can extract the data but the username name is an HASH, there is a way to join this HASH with username?

thanks

It looks like the ‘context_user_id_bin’ column contains the userid from HA with spaces.
To get the user with it in HA:

I don’t think it’s possible directly with SQL.
