rex to export users

[indeed_2000]

Hi
what is the spl command to extract users.

Here is the sample:
2021-09-12 21:40:03,938 ERROR [APPNAME] User H83952 invalid: javax.security.auth.login.LoginException:
2021-09-12 21:40:03,938 ERROR [APPNAME] User 83944 invalid: javax.security.auth.login.LoginException:
2021-09-12 21:40:03,938 ERROR [APPNAME] User A_Frok invalid: javax.security.auth.login.LoginException:

expected output:
H83952
83944
A_Frok

Thanks,

Hi

e.g. this works

...
| rex "User (?<user>[^\s]+)"
