Post CACW with AU Avengers Team
Looking for a fic that's post CACW, the Avengers are hiding out in Wakanda and Tony is home. Betty (I think) turns up about some anomaly/portal and Tony goes to investigate. Some stuff happens and the portal spits out an Alternate Universe Avenger team specifically Cap, Nat, Clint and Thor. Tony expects them to be like his team but they're much kinder and actually sign the Accords. (I dont know if I'm mixing fics but there's a scene where Harley who's in the team votes not to allow them in but is convinced to give them a chance). They attend a gala. Cacw!Steve sees this all happening from Wakanda and the last chapter I recall is them worried about being replaced and making plans to go back.
