Does Gamma’s paid version support Google Tag Manager or HTML editing for GDPR compliance?

Hi! A user of the free version of Gamma informed me that the Gamma tool for creating web pages lacks the ability to edit the HTML code to insert Google Tag Manager tags or privacy clauses as required by GDPR. Currently, there is an option to integrate Google Tag or Meta Pixel through Gamma's tools, but Google Tag Manager doesn't work unless the site is published externally from Gamma, and Meta Pixel records traffic data but it's not possible to add other events to track. I'm asking if these limitations are absolute or if perhaps these functionalities exist in one of the paid versions. Thanks! Alberto
