How to set up prototype setups?

[Martmists-GH]

Example code:

---@alias main_event_popup_window_PopupWindowManager CA7CF9DA40689C95A
---@class CA7CF9DA40689C95A : CDC3F92928A2194E6
---@field private [2] boolean @ popupStop
---@field private [3] C690C42F3FAF568B7
---@field private [4] C8F824939B37A601D
---@field private [5] haxe_ds_List<CA7CF9DA40689C95A_anon_1> @ categories
---@field private [6] C241D29AE0FAE7D57
CA7CF9DA40689C95A = L15_1()

-- snip

CA7CF9DA40689C95A.__name__ = "CA7CF9DA40689C95A"
CA7CF9DA40689C95A.prototype = L15_1()

-- snip

---@param self CA7CF9DA40689C95A
function CA7CF9DA40689C95A.prototype.F20A40E2F8B95D5F6(self, A1_2)
  self[6][1] = CFC8F368D91411014.S36AFB231754F9D91()

  -- How to deal with the following?
  self:FBEC811F36B19972C(A1_2)  -- No such member 'FBEC811F36B19972C' found on type 'CA7CF9DA40689C95A'
