Lua intellisense: show module functions

Module:

local M = {}

--- find users by name
-- @param name string: user name
-- @return object with array of users
function M.find_users(name)
    return {users = {}};
end

return M

Usage:

local userapi = require("userapi")

pcall(userapi.find_users, name)

It works, but intellisense doesn't show me the userapi functions.
