How to use Content Publishing API for Instagram not being Instagram Partner?

Question

We are trying to develop an application for scheduling social media posts. So far we have the Facebook intergration ready, and we are heading to implement Instagram, but according to the official documentation (https://developers.facebook.com/docs/instagram-api/guides/content-publishing) -> "The Content Publishing API is in closed beta with Facebook Marketing Partners and Instagram Partners only. We are not accepting new applicants at this time.". Can you please tell us how we can do a content publishing to Instagram using their API for better scheduling and/or automation? Is the Instagram Partners program closed for good? Can we apply for acceptance? Is there any other way to publish to instagram a bulk of posts (say 30-40) to different accounts if not using the API?

Thanks

This link which is right here might help you publish contents on Instagram, especially, Photos. (Link: https://developers.facebook.com/docs/graph-api/advanced) On the left, check for 'photos upload', there you'll find some methods to publish contents. They've showed it with an example using cURL.

[Edit:] As @rodin's notified, you can now post contents(using Instagram Content publishing API) to instagram without being a facebook partner.
