I use the NodeJS Telegraf package to program my Telegram bot. I'm trying to check if the user is in the channel using the following code:
const channelLeft = await ctx.telegram.getChatMember("@dji_fly_app_hebrew",ctx.message.from.id);
console.log(channelLeft.status)
And I always receive in the status that it is outside... ("left") Even if the user inside the channel... The bot has all access to the channel.
