      The rename oplog looks like this:

      {
        "op" : "c",
        "ns" : "reshardingDb.$cmd",
        "ui" : UUID("2c7b8ac2-9840-4c57-9d1c-4f9905ed1fe3"),
        "o" : {
          "renameCollection" : "reshardingDb.system.resharding.f1b71bc0-6a4c-4cd5-b6ef-ac50e5de3170",
          "to" : "reshardingDb.coll",
          "stayTemp" : false,
          "dropTarget" : UUID("f1b71bc0-6a4c-4cd5-b6ef-ac50e5de3170")
        },
        "o2" : {
          "numRecords" : 0
        },
        "ts" : Timestamp(1627312165, 17),
        "t" : NumberLong(1),
        "v" : NumberLong(2),
        "wall" : ISODate("2021-07-26T15:09:25.358Z"),
        "fromMigrate" : true
      } 
      

      But it gets filtered out because this fromMigrate != true expression is always present, regardless of the showMigrationEvents boolean argument.
