Telepot on python, can't send multiple photos with sendGroupMedia

Question

I'm trying to send 2 or 3 photos at the same time, so they're displayed as one message on my channel. To send one photos I used python's requests library, with this line of code;

pic = {'photo' : open('p.jpeg', 'rb')}
print(requests.get(f'https://api.telegram.org/bot{apiKey}/sendPhoto?chat_id={chat_id}?disable_notification=True', files=pic))

Now to send more at once I use telepot. I'm doing this:

bot = telepot.Bot(apiKey)
bot.sendMediaGroup(
    chat_id=chat_id,
    media=[
        {'media' : open( 'p.jpeg', 'rb')},
        {'media' : open('p1.jpeg', 'rb')}
    ],
    disable_notification=True
)

The problem is I don't precise the type of media being transferred. I tried doing :

media = {'media' :      
                    {'photo' : open( 'p.jpeg', 'rb')},
                    {'photo' : open('p1.jpeg', 'rb')}
        }

But media parameter must be an array.

I also tried to pass a double sized dictionary as argument to requests.get(...), it didn't work either.

Could you guys help me out? Thank you

Well, problem solved, eventually I had to do this:

bot.sendMediaGroup(
    chat_id=chat_id,
    media=[
        {'media' : open( 'p.jpeg', 'rb'), 'type' : 'photo'},
        {'media' : open('p1.jpeg', 'rb'), 'type' : 'photo'}
    ],
    disable_notification=True
)
