How use rider decompile Unity class, and I find UnityEditor.ProjectBrowser#ShowFolderContents, so I use following code to invoke this private method:

    public static void OpenDir(string absPath)
    {
        var assetPath = $"Assets/{RoFile.Rel(absPath, Application.dataPath)}";
        var asset = AssetDatabase.LoadMainAssetAtPath(assetPath);
        var pt = Type.GetType("UnityEditor.ProjectBrowser,UnityEditor");
        var ins = pt.GetField("s_LastInteractedProjectBrowser", BindingFlags.Static| BindingFlags.Public).GetValue(null);
        var showDirMeth = pt.GetMethod("ShowFolderContents", BindingFlags.NonPublic|BindingFlags.Instance);
        showDirMeth.Invoke(ins, new object[] {asset.GetInstanceID(), true});
    }
