Cycleway and sidewalk along a street

I want to tag a street in a correct way: On the left side there is only a seperated cycleway next to the road, on right side of the road there’s a combined cycle- and footway (both have their own lane). How should I tag it?
highway=tertiary (in this case)
bicycle=use_sidepath
cycleway:right=track
cycleway:left=track
sidewalk:right=track

I think, this is wrong. For the right side it should be:
cycleway:right=track
segregated=yes

But this is also wrong - there’s no sidewalk on the left side. Logically the tag should be:
cycleway:right=track
segregated:right=yes

But does such a tag exist?

Do you have photos?

Hello maro21,
thanks for the quick response.
I also made this question in the german part of this forum and received the correct answere:

cycleway:right:segregated=yes

This is exactly what I wanted: A cycleway directly by the road (not a lane on the road) which is also used by pedestrians but divided on the ground by a painted line.
