If you want, you can use a fake name (pseudonym) for the focus group, and you will also be allowed to have your camera switched off so that your face is not visible.
Os dymunwch, gallwch ddefnyddio ffugenw ar gyfer y grŵp ffocws, a gallwch hefyd ddiffodd eich camera fel nad oes unrhyw un yn gweld eich wyneb.
