Hi Maureen - An Assent is in effect a Transfer but complete panel 4 to refer to ASSENT
Panel 5 should list the documents you are lodging so AS1, certified copy probate plus ID3 for yourself as appropriate as you are both the executor and beneficiary.
We don't need ID3 for anyone else so perhaps read through the guidance again to confirm what identity verification is needed -
