This can be done via the CMP API (setting `enableAdvertiserConsentMode` to `true`), website configuration (`window['gtag_enable_tcf_support'] = true`), or app settings. The integration maps TCF Purposes to consent mode commands, such as denying `ad_storage`, `ad_user_data`, and `ad_personalization`. Google tags will default to consent settings if the CMP fails to respond in 500ms or returns an error.\n"]]
