Allowance - how to set that for a Polymarket Wallet?

[cmp-nct]

For someone not deeply familiar with these crypto networks this is a hurdle that's really complicated.

Would anyone have an example how a polymarket wallet (not an external one, created by signing up with an email) can be used to place an order ?
I've searched all I could find, it appears no one ever published any code for this project that actually sets an allowance.

I'm authenticated and set "funder", but here on I am stuck
client = ClobClient(host, key=PK, chain_id=chain_id, creds=credentials, signature_type=1, funder=funder)

I just want to set a LIMIT order for a token_id

1. I've adapted the outdated set_allowances.py and tried to run it, I received an error about insuficient funds.
   That one: https://gist.github.com/poly-rodr/44313920481de58d5a3f6d1f8226bd5e

2. When using signature_type = 1, I get the correct balance, but I also get "invalid signature" when testing the order.
   When using type 2 or -1 then I get a balance of 0.00 but instead of a signature error I get the insufficient balance at the end of the order post.

This shows correct balance but then resp = client.post_order(signed_order, OrderType.GTD) will bug out with "invalid signature"

client = ClobClient(host, key=PK, chain_id=chain_id, signature_type=1)
client.set_api_creds(client.create_or_derive_api_creds())
b = client.get_balance_allowance(params=BalanceAllowanceParams(asset_type=AssetType.COLLATERAL))

This shows no balance, but the post_order() will not complain about the PK/signature, in this case it says "no allowance"
client = ClobClient(host, key=PK, chain_id=chain_id, signature_type=2)

@cmp-nct I am also struggling to understand when and how to use the Proxy Wallet and when the EOA. (https://docs.polymarket.com/?typescript#signature-types)

How did you solve updating the allowance and using a ClobClient to place orders with valid signature?
