How to buffer request with Transfer-Encoding: chunked

[vlntsolo]

Running Django in WSGI mode, but a third-party service sends callbacks with Transfer-Encoding: chunked header, with request body starting with chunk size:

`POST /api/services/callback/ HTTP/1.1
Host: eXX4-1XX-129-XX-104.ngrok-free.app
User-Agent: Apache-HttpClient/5.3.1 (Java/21.0.5)
Transfer-Encoding: chunked
Accept: application/json
Accept-Encoding: gzip, x-gzip, deflate
Content-Type: application/json
X-Forwarded-For: XX.XX.XX.XX
X-Forwarded-Host: eXX4-1XX-129-XX-104.ngrok-free.app
X-Forwarded-Proto: https

272
{"paymentReference":"XXX", "errorCode":null}
0
`

Is there a way to convert it into a buffered request, with clean body without 272 starting and 0 closing lines?
