Best Apps to Manage AI Agents for YouTube Creators

Hi, I'd like general advice on the best app to use to trigger and respond to my ai agents from my phone. I'm a professional youtuber making space/astro videos and I'm hoping ai will help me navigate comments and blogs and videos across all my social media channels. Slack is not something I particularly want to use as it seems i have to pay for it. Discord would be a good option but the only trigger for the discord intergration in Lindy seems to be "New guild member" . Surely a comment in a channel trigger would be good. Am I missing something? Whatsapp requires a secondary mobile number which will be a pain to set up. Telegram - I don't use it but maybe.... Many thanks in advance for your help.
