LFG Applicant Tooltip hook?

[Healingz]

Hi,

Complete addon newbie here. I was wondering if it was possible to add text to the LFG applicant tooltip in a similar way as player mouseover tooltip?

local function testText(self)
local name, unit = self:GetUnit()
    if unit then
        GameTooltip:AddLine("New Text Added!", 1, 0.49, 0.04)
    end
end
GameTooltip:HookScript("OnTooltipSetUnit", testText)

This works fine but was wondering how i could adapt this to the LFG applicant tooltip as well.

Thanks!
