With the ( and ) surrounding the text, you can use string.match:

str = "Hello (new text)"
print(str:match("%((.+)%)"))

%((.+)%)") is a pattern that captures every character between the ( and ).

The easiest way to do this is just to cancel out the Hello in your string.

local msg = "Hello (obama)"
msg = msg:gsub("Hello %(", ""):gsub("%)", "")

If the first part of the string is dynamic and is not always hello you can try this:

local msg = "Bye (obama)"
local pattern = "%p.+%p"
print(({string.match(msg, pattern):gsub("%)", ""):gsub("%(", "")})[1])

This soloution may not be the best and most efficient but it certainly works. I hope it helped you. Let me know if you have any questions.
