No addon option for extra indexes in free plan

Describe the bug

It mentioned in the website that you need to pay 0.9$ per 1000 documents "$0.9 Per Extra 1000 Docs (max 5K)" and each project in free plan can only have 500 documents. So i went to the upgrade section and found the addons dropdown. But from the dropdown I couldn't find any place to purchase extra documents for my project. What can i do now?

To Reproduce

1. click on upgrade from the dashboard 2)view the addon of the project

Expected behavior

1)expected to see an option to purchase extra document as mentioned in the website under the free plan
