Add an option to configure Consent Modes for GDPR compliance

[razaanstha]

It would be great to have a new setting in the plugin called "Revoke consent until user confirmation." This would add the fbq('consent', 'revoke'); command to the Facebook Pixel on the frontend. This way, developers can handle consent management based on their chosen CMP services or custom popups/logics, ensuring the site meets GDPR requirements and send data to Meta only with user consents.
