Ireland to join the Crown British Commonwealth of Nations, has is it already been decided ?

(n.b. Video should say "Ireland joined the UN Security council in 2020/2021" (not 1920/1921) After Irish General Michael Collins signed the Anglo - Irish treaty for a partition of 4 Counties in Ulster in December 1921 it became 6 counties after his death. His subsequent assassination and the following boundary commission of 1925, enlarged the 4 counties of Ulster to become 6 counties instead.(the boundary commission had Irish and Unionist members) Eamon De Valera and British General Smutts corresponded on the issue prior to 1921/1922. General Smutts was heavily involved in the Irish negotiations for Britain (but is rarely mentioned such), it is suggested that Ireland never really left the Commonwealth, (under any political party including Sinn Fein) and that is still an ongoing part (as under the Crown) of the “realpolitik” in the UN (commonwealth) in which Ireland joined the UN Security council in 2020/2021. Prince Charles vying to become King Charles 3rd, with the WEF (World Economic Forum who controlled all political parties in the ongoing pandemic) will look to expand the Commonwealth. A national Referendum r.e. joining the commonwealth could occur in Ireland or it may be decided by parliament vote alone.
