Proof Of Shop/Commercial Estbalishment Opening While Shops And Establishment Registration In UP

Hi,
I am trying to get shops and establishment registration using the online portal for the same at Labour Act Management System
The online registration form at is asking for " Proof Of Shop/Commercial Estbalishment Opening ". I want to know what documents can be submitted as proof of shop opening for a proprietorship ?
Please see the attached snapshot of the form for reference. In the attachment section the first upload option states " Proof Of Shop/Commercial Estbalishment Opening ".

Trade licence ( certificate of establishment) issued by locl mucipipal body in urban ( gram panchayat in rural) is the prooof of establishment.
