Change Default Username and Password in Aggregate

In our application, we are utilizing ODK-AGGREGATE. When setting up the docker container for the odk-aggregate-server, we would like to have control over the default login credentials (which are currently set as "administrator" for the username and "aggregate" for the password). Our intention is to define our own preferred credentials in the .env file. Consequently, upon container setup, the administrator should be able to log in using our specified credentials instead of the default ones. I have managed to change the username using the file, but I haven't found a way to modify the password. Even if we alter the username, the password remains unchanged as "aggregate," which only partially solves our problem. Could anyone please advise me on how to change the default password along with the username?
