How can I change the Netflix profile on the TV?

Yesterday I was able to load Netflix on my older TV. But my main profile was automatically displayed and now I do not know how to change the profile. I would like to look at my laptop with my profile so that my mother can look at the TV with a different profile and we can be on Netflix at the same time. I also noticed that I still have the old Netflix logo on the Smart TV, so with the white font and the red background.

How can I change the profile?

Update.

I think if you go in the movie overview to the left, then goes from the left bar, where you can sort by genre, etc.

There's the picture of your profile at the top. There you can change it.
