List of Yaml env variables

[kmilo9999]

Hello,

While reviewing the librechat.yaml example, I noticed that the customWelcome field uses a variable like {{user.name}}, for example:

customWelcome: Hey {{user.name}}! Welcome to LibreChat

Where is this variable coming from and Could you please let me know where I can find the list of available variables that can be used in the YAML configuration file?
I remember seeing them in the documentation, but it got updated a few weeks ago and I cant seem to find them.

Thanks
