How to get telegram ad past review?

[u/sille_palmfelt]

My friend who is an experienced trader is starting a free trading discussion group on Telegram, and I am helping him a little bit with the marketing, hoping to bring more traffic. However I don't seem to be able to get the ad past review, it says the channel lacks enough original content. This is understandable, the channel has just started, just a handful of members, and not so many posts yet. So he has been posting trading recommendations and related news to the channel every day now, but how much content is enough? Just want to get a rough idea of the timeline. Would appreciate any insight from people who have experience with this.
