How to post on Instagram via a script?

Hi there,
I hope everyone is holding well during this difficult time. So, today I was got a little side-tracked from my original project and started working on something else. An Instagram bot. Now, wait don't bite me. I know there are many, but I wanted to try by myself.
This is part of a bigger problem. Half of it I have solved the remaining is this:

I have some images on my Google Drive and now want to post on Instagram from my account.

I couldn't find any working solution. It is broken as Instagram is very strict against automation. Every time there is one problem or another.

I think the major problem is that I am trying to post with Google Colab. It posts from a new location i.e. Google HQ(Mountain View, CA). Instagram flags it as suspicious access.

Finally, what I am looking for is a
Javascript or a python script that can post images on my account from google drive without getting banned obviously.

You may ask why I am not using apps that are already there? : because I want to run these scripts as CRON jobs on an EC2 instance or something else on in VM on AWS or GCP so that I don't have to worry about running them manually. Once set up, they would regularly post on my behalf.

Thanks for reading this.
