How to generate a signature with web3py like metamask does?

Question

Most ethereum apps request signatures like this

How exactly do i recreate this signature in web3 py? Is there any way i can view the data that gets sent thru metamask?

I have tried the following code without success:

message = encode_defunct(text='Swap 0.04 ETH Minimum: 21.64184785 ZKS To: 0xc6f8a2d663250ad86c6c58fc310238e1e5e457d6 ChainId 10 Nonce: 14 Fee: 0.0 ETHAccount Id: 75463')
signed_message = w3.eth.account.sign_message(message, private_key=private_key)

Metamask has several api signatures.

There is a draft of the current specification at EIP 712.
