Authentication Built in Password - Import

I am New to EMQX
Wanted to know how to import username and password from csv file.

Using Built in Password with Password hash as SHA 256 and salt position suffix.
In this scenario. how to import my regular username and password fields.

or does this scenario support importing.

I am looking this if in case i have more username and password. its easy to import rather creating each one by one.

thank you
