Zoom-lens add-on for iPhone 13Pro?

Does anyone know of a quality add-on lens with attachment and tripod that can do serious zoom that goes out to anywhere near 300x? I'm going on a long term trip and am trying to save weight by not bringing my big camera with me. I will also be going on safaris, so would like to have some significant zooming abilities. I've looked online quite a bit, and most have reviews that criticize the lens, attachment, and tripod qualities. If I can find a good one, I will buy that and an iPhone13 Pro. Has anyone found anything like what I'm describing that is any good?

I'd love any feedback from people who have had success with long-range zoom add-on on an iPhone 13 Pro.
