Hello,

Can I have a response about this PR please ?
I can work more on it, but for research project I'm really needing it.

Please feel free to give me feedback, even negative feedback, please.

Hi @J4YF7O, I'm sorry about it taking so long to reply.

This is a great PR! What remains to be done on it, or can I merge it directly?

Hello @quad,

I'm sorry about it taking so long to reply too

I think that when the PR was pushed it was complete.
More than a year later, I am not so sure that all is still compatible with the whatsapp evolution.

Unfortunately I don't work for the above mentioned project anymore, and I don't have enough time to do the necessary tests to merge it.

If someone wants to take it over, they should check that the get_chat_history (on backend/whatsapp.py) method is still working. (and resolve conflicts...)

Otherwise you can close the MR.
