Téléviseur intelligent Sharp

Good evening,
Actually, it's quite complicated, I'm struggling too because apps for Sharp smart TVs are nonexistent. Unlike other brands that have apps for that, you can send photos and videos to play on the TV directly through the app on the TV, and bam, no problem or very few.

For Sharp TVs, there's DLNA, which is just okay, and Miracast; but the thing I can do is connect my iPhone to the TV and play what's on my iPhone only from the TV, but I can't send something directly from my iPhone to the TV.
Also, iOS is closed, not the best like Android. With my Samsung tablet on a Samsung TV, it's definitely better.

Another solution is to be on a Freebox so we have AirPlay without any issues; we can send whatever we want from the iPhone.

So, it's not much but better than nothing. With Sharp TVs, you feel like you're on an old Windows, let's be nice and say 95/98...
I have a Sharp TV that I recently purchased, it's the model: LC-32FI5342E.

Hello, there is nothing about this in the instructions.
