Customization in Swift ArgumentParser's help command and error output

Hello I want to implement customisation to swift argumentparser, Here are following changes want to do it in my cli

1. changing default footer present in help command output

currently help command output coming like this

OVERVIEW: clisample

USAGE: clisample <subcommand>

OPTIONS:
  --version               show the version.
  -h, --help              show the help.

SUBCOMMANDS:
  logs (default)          Export logs for clisample processes.
 
See 'clisample --help' for more information.'

so instead of

See 'clisample --help' for more information.'

I want my own string

For more details, run 'clisample help <subcommand>'

1. customise error string getting from validation error

Error: Missing value for '-t <time>'
Help:  -t <time>  Time window (e.g. 10h, 30m, 2d).
Usage: clisample logs --time <time>

  See 'clisample logs --help' for more information.

so I want error output with example and customised footer, like this

Error: Missing value for '-t <time>'
Help:  -t <time>  Time window (e.g. 10h, 30m, 2d).
Usage: clisample logs --time <time> 
Example: clisample logs -t 5m

  For more details, run 'clisample help <subcommand>'

Is this changes possible from anyway?
