Is there a documentation about using CEL in AuthConfig ?

The question is title.

Only in the CRD, I'm afraid. But we definitely need some for GitHub and the public website too.

In the meantime...

1. Where previously one could do {selector: <json-path>, operator: <authorino-custom-operator>, value: <string>}, now {predicate: <cel-predicate>} is also supported, where <cel-predicate> has to evaluate to a boolean value;
2. Where previously one could do {selector: <json-path}, now {expression: <cel-expression>} is also supported;
3. Specific fields that supported JSON path interpolation (e.g. http.url: <string>) have got a CEL-enabled counterpart (e.g. http.urlExpression: <cel-expression>).

All CEL predicates and expressions must be valid or the AuthConfig will be rejected (at reconciliation time), unlike JSON paths that at runtime will evaluate to null/empty value if invalid.

Thnx @guicassolato
Would be great to have all this in User guides.
