Cannot upload on discord bigger than around 14 MB

Hello!

New creator here, I would like to automate my instagram videos and pictures.
I followed this for guide: Instagram Automation and AI Automation: Make.com Tutorial for Posting Reels

But the discord part fails for me as it does not allow to upload videos bigger than ~14 MB.
I have the subscription for discord and I can upload directly with ease 120 MB sized videos.

Can you please help me out here? If there is a better option than discord to use for public URL (for insta) i would appreciate. Thanks in advance!
