Where finding available conditions for Termination Approval rules

Summary:

Content (required):

Hello experts,

we should configure termination approval rule. Where could I find the list of condition I can use?

In the attached example you can find Legal Employer, but where I find other parameters?

For example, according to the termination reason the termination should be approved by specific users?

Is termination reason available as condition?

Thanks in advance for your time!

Kind Regards,

Valerio
