Online discussion group arranged in wine bar (7)

I believe the answer is:

webinar

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

'online discussion' is the definition.
(I've seen this before)

'group arranged in wine bar' is the wordplay.
'wine bar' can be anagrammed to 'WEBINAR'.
However, I'm unsure how the anagram is indicated.

Can you help me to learn more?

(Other definitions for webinar that I've seen before include "online discussion" , "Internet seminar" .)

I've seen this clue in The Times.
