✅ C# 14 extension indexers?

There are extension properties and extension statics, but is it possible to write extension indexers? I've tried the following, but it says "this member is not allowed in an extension block".

extension(DataGridViewRow row)
{
    public DataGridViewCell this[int i] => row.Cells[i];
}

extension(DataGridViewRow row)
{
    public DataGridViewCell this[int i] => row.Cells[i];
}
