How to add the consent panel to pages?

Issue

I would like to know how can I add the consent panel to pages to comply with the directives mentioned below:
- "To comply with the regulations governing cookies under the GDPR and the ePrivacy Directive, you must: Make it as easy for users to withdraw their consent as it was for them to give their consent in the first place."

The consent panel can be added to any page as a portlet, that can be shared anyhow or can be inserted into the navigation menu.
