Happened to me, the following is the header I got from HTTP Header Live extension:

POST: HTTP/1.1 201

Host: ________
User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:121.0) Gecko/20100101 Firefox/121.0
Accept: */*
Accept-Language: en-US,en;q=0.5
Accept-Encoding: gzip, deflate
Content-Type: application/json;charset=UTF-8
token: ____________________
Content-Length: 160
Origin: http://_______
Connection: keep-alive
Cookie: _token=_______

edge has no problem to catch and show this request information.
