Help requested - Applying for PBS, Start-up, Innovator or Global Talent – Partner (wife) visa and child visa

Dear All
I have been recently awarded with Global Talent Visa.
Now I want to apply for my Wife and Child visa as well who are outside the UK.
But I have a few queries regarding this and If anyone can guide me I will be grateful.

First, when I am filling up my wife's application at the start it says

Which visa has Josh applied for or been granted? Global Talent visa - stage 2
Do you have one of these reference numbers? (Required)
Yes, I have their UAN
Yes, I have their Home Office reference number
Yes, I have their VAF number
Yes, I have their GWF number
No, I do not have any of these reference numbers for them

My question is that I have the BRP number with me but there is no option to enter it.
I have the UAN number so I should enter this?

- in the mandatory documents to be attached they say provide **Evidence of continued relationship while living apart or outside the UK**.
As she will be joining me after 5 years so marriage certificate will be enough?


Secondly, when I am filling up my child's application at the start it says

Which visa has Josh applied for or been granted? Global Talent visa - stage 2
Do you have one of these reference numbers? (Required)
Yes, I have their Home Office reference number
Yes, I have their VAF number
Yes, I have their GWF number
No, I do not have any of these reference numbers for them

I don't have any of these, I have only the BRP number and the UAN number. So what should I select from the above?

- Your parent's or legal guardian's details
Who is your parent or legal guardian who has given consent for you to make this application?
Will it be me or her mother or both?

If anyone can guide me I will be grateful.
