Is it possible to detect group info?

You can go on on ROBLOX wiki and using an Service name GroupService

You can use this like that

local groupId = 377251
local group = game:GetService("GroupService"):GetGroupInfoAsync(groupId)
 
print(group.Name .. " has the following roles:")
for _, role in ipairs(group.Roles) do
   print("Rank " .. role.Rank .. ": " .. role.Name)
end

I take this from wiki, if you want ot know more about GroupService or GroupInfo You can go on roblox wiki here
