Help me post a large unity / android project on playstore

Job ID: 32272888

Budget: $30 – $250 USD

I am having trouble posting a unity/ android project greater than 150 Megabytes on the play console.
I am building an AAB that is 200 MB. I researched Play Asset Delivery but it doesn't appear to be simple.
I also read about apk expansion files but can't figure out how to upload them to the play console.
