How to refresh new Blizzard_Menu?

[wmcarlos]

I have the following code for adding a button to the context menu:

Menu.ModifyMenu("MENU_UNIT_PLAYER", function(ownerRegion, rootDescription, contextData)
    local button = MenuUtil.CreateButton(L["OFFER_TOOLTIP"])
    rootDescription:Insert(button, 13)

    button:SetResponder(function(data, menuInputData, menu)
        ns.SendAddonMessage("offer"); DEFAULT_CHAT_FRAME:AddMessage(L["OFFER"], 1.000, 1.000, 0.000)
        return MenuResponse.Close
    end)

    button:AddInitializer(function()
        if not UnitAffectingCombat("player") and not UnitAffectingCombat("target") then
            if unit.playable then
                button:SetEnabled(true)
            elseif UnitIsSameServer(UnitName("target")) and not unit.playable then
                button:SetEnabled(false)
                button:SetTooltip(function(tooltip, elementDescription)
                    GameTooltip_SetTitle(tooltip, MenuUtil.GetElementText(elementDescription));
                    GameTooltip_AddErrorLine(tooltip, L["NO_ADDON"]);
                end)
            elseif not UnitIsSameServer(UnitName("target")) and not unit.playable then
                button:SetEnabled(false)
                button:SetTooltip(function(tooltip, elementDescription)
                    GameTooltip_SetTitle(tooltip, MenuUtil.GetElementText(elementDescription));
                    GameTooltip_AddErrorLine(tooltip, L["NO_PARTY"]);
                end)
            end
        else
            button:SetEnabled(false)
            if UnitAffectingCombat("player") then
                button:SetTooltip(function(tooltip, elementDescription)
                    GameTooltip_SetTitle(tooltip, MenuUtil.GetElementText(elementDescription));
                    GameTooltip_AddErrorLine(tooltip, L["PLAYER_IN_COMBAT"]);
                end)
            elseif UnitAffectingCombat("target") then
                button:SetTooltip(function(tooltip, elementDescription)
                    GameTooltip_SetTitle(tooltip, MenuUtil.GetElementText(elementDescription));
                    GameTooltip_AddErrorLine(tooltip, L["UNIT_IN_COMBAT"]);
                end)
            end
        end
    end)

But I need the menu to update when receiving the callback, if it is open:

EventRegistry:RegisterFrameEventAndCallback("CHAT_MSG_ADDON", function(_, prefix, text, channel, sender, _, _, _, _, _)
    if prefix == "testing" then
          if text == 'offer' then
          ns.SendAddonMessage('playable')
          elseif text == 'playable' then
                                   <— refresh is needed here.
          end
    end
end)

I tried to somehow use MenuResponse.Refresh, but it doesn't work outside the SetResponder construct.

For example, in this case, the menu updates when I click the button I added:

    button:SetResponder(function(data, menuInputData, menu)
        return MenuResponse.Refresh
    end)

But I haven't found another way to make the menu update without using SetResponder.

I would be very grateful if someone could help me.
