How to insert a new policy active scan in patch folder ZAP JENKINS

[Dario GYM]

Hello;

In Attack Mode >> Active Scan >> Policy, When I click on INFO ICON I read this message:

"Select a ZAP policy to use for the Active Scan. The policies must be stored in the Path provided for 'ZAP Settings'. "Default Policy" is used if no policy is specified.

(from Official OWASP ZAP Jenkins Plugin)"

BUT I haven't found no online guides to insert a new policy inside patch folder ZAP JENKINS:

1. Where is installed the default policy path?

2. How to modify and insert a new file to define new active policy?

3. There is a guide online to insert the script correctly?

Thanks.
