Popular Omani covered up nose (5)

I believe the answer is:

aroma

I'm a little stuck... Click here to teach me more about this clue!

'up nose' is the definition.
'aroma' can be an answer for 'nose' (I've seen this in another clue). I'm unsure of the 'up' bit.

'popular omani covered' is the wordplay.
'covered' indicates the answer is hidden within the clue (the answer is covered up by the clue).
'AROMA' can be found hidden inside 'popular omani'.

Can you help me to learn more?

(Other definitions for aroma that I've seen before include "Strong smell" , "Perfume" , "Distinctive odour" , "particular charm" , "Odour, mostly pleasing" .)

I've seen this clue in The Guardian.
