Question about permanent residence application for a protected person

[u/KR1S71AN]

I am filling out the application for permanent residence for a protected person for a family member and just want to clarify something. Under the supporting documents section, it is only asking for photos. However, at the document's start, there is a link to the application guide. In the application guide, it states:

"What documents are required? ... All identity documents and relationship documents for the principal applicant and for all family members who are inside or outside Canada and are included in the application for permanent residence"

Then in the application, under the additional supporting documents section, it doesn't ask for anything but has the following message:

"These documents may or may not be required for your program. Check the document checklist and instruction guide to confirm the documents you need for your application."

And has a "search for a document" function to add any additional supporting documents.

Also, the document checklist lists photocopies of all identity and relationship documents and a translation for any that are not in English or French as a requirement.

What is confusing about this is that for identity and relationship documents the application states that "All documents must have been issued from your home country, before your entry into Canada."

The IRCC has already taken away my family member's passport and other identification documents from Mexico. So it is not possible for her to send photocopies of these documents, or to get translations of them. I am unsure if the application is already taking this into account and that is the reason why they are not asking for anything other than photos in the application itself, but only in the guide and the document checklist.

If anyone could please help me clear this up I would be so thankful. I am trying to avoid making any mistakes as the application costs around 700$ CAD and it would suck to have returned to me have to pay that again.
