I have a query about GMC

I have a query about GMC .I applied for it online and fot the email that states the required documents that I need to submit . One of the required document is employer referrences. I am confused about it. I moved to KSA from Pakistan. My job in KSA started on May 2019 .By that time I had Saudi Health Council (medicl registration body in KSA) “accredation”. Here if you are not working you can’t get full registration, you’ll have “accreditation” and then when you get a job, the hospital will apply for your registration with Saudi health council. I got that in October 2019. Now my questions are,

  1. Do I need to get this form filled?
    2.If yes, I’ll get it filled only by my saudi hospital only or from Pakistan too? As I used to work in Pakistan until 2017.
    (I have both Pakistan medical commission and saudi health council registration)
    3-Do I need to mentiom that I was working with saudi health council “accreditation” and got the registration after few months?
