Looking for GTM Sequencer Tools for Social Media Campaigns

Hi, just asking anyone in the community to see if you have used any GTM sequencer tools you guys have used for social media outreach campaigns like X, Facebook, Instagram, Tiktok? if yes, please list them, curious to know. and how about using tools like N8N or Make to help automate the management of online groups or communities like discord, slack, reddit? curious to no that too 😊 Saw job posting on linkedIn that involves task similar to that.
