Problem with IFTTT bot?

Question

IFTTT

Hello. I wanted to connect my instagram store with a telegram channel. Previously, I had no experience working with bots, so I clearly followed the instructions. I successfully connected to the IFTTT bot, went through all the steps, connected both the channel and Instagram using the telegarm applet. Then, for verification, I posted a post on insta, silence on the telegram channel. created an applet according to the instructions, re-made a post on insta, silence in the telegram channel. there is a bot in the channel admins in the telegram. on instagram in active applications, the bot is. Why can't I duplicate posts on Instagram on my telegarm channel? public channel. What did I miss?
