Configuration
Cookie consent could be handled by a cookie module or an external service like Cookiebot or similar, henceforth ( CMP ).
The ( CMP ) is who stores and updates the user's consents; Depending on how the service is implemented, it will handle those consent requests by consent web API or by a custom GTM deployment.
If your ( CMP ) integration is by a PrestaShop module, be sure that is compliant with the Google API web consent, more info...
Note
Ask the ( CMP ) module developer before purchasing.
If your implementation is by an external service, read the provider documentation in order to properly deploy the consent request by each visitor, usually by a custom GTM implementation.
Regarding this module and the GTM workspace implementation it is not necessary to apply any special action; once the ( CMP ) is properly deployed, GTM will adapt the tag behavior accordingly.
