Speaking at high profile events

Hi everyone,

Does speaking in a peer reviewed conference with more than 100 attendees fall under the following category of Mandatory criteria:

  • You have evidence of speaking at high-profile digital technology sector events, or specialist events for your particular field in the digital technology sector, as evidenced by reference letter(s) from leading industry expert(s) describing your work, or as evidenced by news clippings or similar evidence (including event size/attendance estimates where possible).

I can provide evidence with speech video link (Youtube), participation certificate, and letter from the organizing body detailing why I was invited for the talk on the basis of my work.

Specifically, the confusion I have is whether to use it for OC4 or for the mandatory criteria.
