Game show at the heart of network (4)

Ross

I believe the answer is:

mesh

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

'network' is the definition.
(I know that network can be written as mesh)

'game show at the heart' is the wordplay.
'MESH' is hidden within the letters.
However, I'm unsure how the hidden word is indicated.

'of' acts as a link.

Can you help me to learn more?

(Other definitions for mesh that I've seen before include "Web" , "harmonise" , "Interconnected configuration" , "Knit or weave for Shem" , "Netting made of wire or thread" .)

I've seen this clue in The Irish Times.
