Wordpress to Instagram post/story HARD Rejected

I have made a useful plugin (at least i think)
it’s post from wordpress to instagram automatically -> it also posts on stories with clickable link* so that your visitor can open directly from instagram.

Here is a demo of the plugin:
Username: demo
Pass: demo123

Can you please help me let know why it’s getting hard rejected so that i make it as brand new features!

here is the free plugin on wp directory
