How to get response body when using proxy_intercept_errors

I have a requirement where when proxied response error code is 401
(condition #1) and response body has text "SAML Token Expired" (condition
#2), I need to intercept it and redirect to refresh token API.

I could do it partially where only error code 401 is considered. Not able to
find a way to read response body text to give condition #2:

"location /service {
   proxy_intercept_errors on;
   error_page 401 = @refresh;
location @refresh {

   (# Here check if the response body has text "SAML Token Expired". If yes
return 401 directly.)

   set $original_uri $scheme://$http_host$request_uri;
   return 307

Please help me on getting the response body text. Thanks in advance!
