SOAP request works in SOAPUI but fails in Python using Requests library

I am facing an issue while making a SOAP request from my Python code. I tested the same request using SOAP UI, and it worked successfully. However, when I tried to replicate the request in Python using the Requests library, it didn't work

(I should add that I have already made other requests that worked both in SOAP UI and Python, but none of them involved a bearer token)

first i pass the wsdl is:

import requests
endpoint = "https://externalchannels-pro- 
ws.gruposancorseguros.com/Brokers/Document/DocumentService.svc?wsdl"

then i pass the body and bearer token:

auth="""Bearer eyJhbGciOiJSUzI1NiIsIn..."""
    
body="""<soap:Envelope xmlns:soap="http://www.w3.org/2003/05/soap-envelope" xmlns:tem="http://tempuri.org/" xmlns:san="http://schemas.datacontract.org/2004/07/SancorSeguros.Services.Contract.Document" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
       <soap:Header>
       </soap:Header>
       <soap:Body>
          <tem:GetCertificateDocument>
             <tem:request>
                <san:Branch>1500</san:Branch>
                <san:CertificatNumber>2</san:CertificatNumber>
                <san:Document>ConstanciaPolizaArgentina</san:Document>
                <san:OfficialNumber>349947</san:OfficialNumber>
                <san:ReferenceNumber>264448</san:ReferenceNumber>
             </tem:request>
          </tem:GetCertificateDocument>
       </soap:Body>
    </soap:Envelope>"""

Then i make the request:

headers = {"content-Type": 'application/soap+xml;charset=UTF-8;action="http://tempuri.org/IDocumentService/GetCertificateDocument"', 
                   "Accept-Encoding":"gzip,deflate",
                   "Accept":"*/*",
                   "Connection":"Keep-Alive",
                   "Host":"externalchannels-pro-ws.gruposancorseguros.com",
                   "Authorization":auth
                   } 
           
response = requests.request("POST", url=endpoint, data=body, headers=headers)
      
print(response)
print(response.content)


    

This returns:

>>> print(response)
<Response [500]>
>>> print(response.content)
b'<s:Envelope xmlns:s="http://www.w3.org/2003/05/soap-envelope"><s:Body><s:Fault><s:Code><s:Value>s:Sender</s:Value></s:Code><s:Reason><s:Text xml:lang="en-US">No es posible finalizar la operaci\xc3\xb3n, favor intentar nuevamente. Activity: 00000000-0000-0000-0000-000000000000</s:Text></s:Reason></s:Fault></s:Body></s:Envelope>'

I used httptoolkit to compare the requests and noticed that SOAP UI adds some lines to the SOAP request. I added the same to my Python code, but it resulted in a different error.

import requests

I compared the requests again and confirmed that the bearer token and the code match. I suspect that SOAP UI may have some mechanism to verify the token correctly, but I haven't been able to figure it out. I would appreciate any assistance as I have been struggling with this issue for several days.

This Are the soapui request working headers:
