Solo proprietorship application review says - incomplete

Hi @IntegrationSupport , @admin,
I have applied for sandbox integration under solo proprietorship but the review that i have received is of incomplete application.
I just wanted to know what elements are lacking in my application, so that I can put it in.

Thanks for your quick and prompt response and looking forward to you reply.

Thanks & Regards,
