AlmaLinux 8.10 - Varnish secret File Problem..

[blackstar]

I am using "AlmaLinux release 8.10". I use the "Purge Varnish" plugin on WordPress. but there is no secret file. How can I create this?

I am using cwp pro. web servers: nginx-varnish-apache..

Is there a different way to clear cache?

thank you..
