For this, it is better for you to start from the Wild West aka Telegram.
Start a telegram group, update the group with the content and links and everything that goes with your marketing funnel plan.
Make a list of your competitors' telegram groups, then all that's left is to scrape telegram members from your competitors' groups and add them to your group.
To increase visibility and maintain constant movement it is recommended tob build several such telegram groups under your brand so you don't put all your eggs in one basket.
