Documents in Zoho Projects with more than 25 users?

Documents in Zoho Projects with more than 25 users?

Is the documents panel in zoho project independent of zoho docs? If I have more than 25 people in a project do I need to purchase zoho docs in order to have them all have access to my documents?

I would like to have multiple users in Zoho Projects (+25) be able to co-author documents in Zoho projects and I am wondering if I am required to buy Zoho Docs in order to do so.
