Calculate average in interface

[Divya_Shah]

I've built a scheduling app on the Airtable interface. While the interface is ready I realised I cannot give open access to users to use my app as they all have to be on my paid plan from my understanding. 

Can someone guide me on how I should make it accessible to all. I thought of setting up authentication in bubble and embedding the interface there with forms so that the user can update the info but I cannot find embedding code for interface without making it public. 

this is urgent please

Currently only publicly shared Interfaces can be embedded I believe, and so any embedded Interfaces are read-only I'm afraid
