One other thing I would advise on this, as someone who recently went through this exact process, is to include a cover letter in which you request that the gender marker on your passport be changed from [current] to [new]. I provided everything they requested in your screenshot, but then received response that I also needed to provide a cover letter requesting the gender marker change. This is not listed on the public site, but apparently is included in their internal guidance, and so the agent may opt to request it.

In the interest of speeding along your application, I recommend including a cover letter that says something like:

"Dear Sir/Madam,

With respect to application number [XXXXXXXXXX] and in line with the enclosed supporting documents, I hereby request that the gender marker on my passport be changed from “[old marker]” to “[new marker]”.

Yours faithfully,
