How to sign transaction in Tron network with trongrid API 4.7.2 and Python?

Question

I have call this post API in Python:

url = "https://api.trongrid.io/wallet/createtransaction"
headers = {
    "accept": "application/json",
    "content-type": "application/json"
}
body = {
    "owner_address": "Txxxxxxx",
    "to_address": "Tyyyyyyyy",
    "amount": 100_000,
    "visible": True
}

So in response we get transaction data like this:

{'visible': True, 'txID': 'b6b4b95a4864b9a93a9686ae9dccb2e71d415f611da68d80ec75e3e366488s77', 'raw_data': {'contract': [{'parameter': {'value': {'amount': 100000, 'owner_address': 'Txxxxxxx', 'to_address': 'Tyyyyyyyy'}, 'type_url': 'type.googleapis.com/protocol.TransferContract'}, 'type': 'TransferContract'}], 'ref_block_bytes': '2c65', 'ref_block_hash': '3d73328b7ccf78s3', 'expiration': 1693055346000, 'timestamp': 1693055288583}, 'raw_data_hex': '0a022c6522083d73328b7cxxxxx'}

So we can use second API

https://api.trongrid.io/wallet/gettransactionsign

To sign transaction with private key, But in 2023 this API depricated and not supported anymore.

So i need to know what is the best alternative for this API?
Run new node on my own server? If this is best way, tell me how?
Do it offline? Is it possible and how?
Or any suggestion.
