Instagram API: view and backup direct messages from a web browser

Instagram API: view and backup direct messages from a web browser
1) Log in on Instagram web version and go to your profile page
(the home page will not work because it loads data when scrolling down and the direct messages will be displayed at the bottom of the page)
2) Modify HTTP headers with a browser addon like Header Editor (https://addons.mozilla.org/en-US/firefox/addon/header-editor/)
Content-Security-Policy (response header on domain www.instagram.com): original data with https://i.instagram.com/ added to connect-src
report-uri https://www.instagram.com/security/csp_report/; default-src 'self' https://www.instagram.com; img-src https: data: blob:; font-src https: data:; media-src 'self' blob: https://www.instagram.com https://*.cdninstagram.com https://*.fbcdn.net; manifest-src 'self' https://www.instagram.com; script-src 'self' https://instagram.com https://www.instagram.com https://*.www.instagram.com https://*.cdninstagram.com wss://www.instagram.com https://*.facebook.com https://*.fbcdn.net https://*.facebook.net 'unsafe-inline' 'unsafe-eval' blob:; style-src 'self' https://*.www.instagram.com https://www.instagram.com 'unsafe-inline'; connect-src 'self' https://instagram.com https://www.instagram.com https://i.instagram.com https://*.www.instagram.com https://graph.instagram.com https://*.graph.instagram.com https://*.cdninstagram.com https://api.instagram.com wss://www.instagram.com wss://edge-chat.instagram.com https://*.facebook.com https://*.fbcdn.net https://*.facebook.net chrome-extension://boadgeojelhgndaghljhdicfkmllpafd blob:; worker-src 'self' blob: https://www.instagram.com; frame-src 'self' https://instagram.com https://www.instagram.com https://staticxx.facebook.com https://www.facebook.com https://web.facebook.com https://connect.facebook.net https://m.facebook.com; object-src 'none'; upgrade-insecure-requests
User-Agent (request header on domain i.instagram.com)
Instagram 85.0.0.21.100 Android (23/6.0.1; 538dpi; 1440x2560; LGE; LG-E425f; vee3e; en_US)
3) Run the following JavaScript code in the web console of your browser or in a tool like Firefox scratchpad.
The function InstagramDMthreads should be used first, then you have to comment the call to it and uncoment the call to InstagramDMmessages,
which takes a thread ID as parameter (found with the previous function InstagramDMthreads).
A textarea will appear to the bottom of the page so you can copy-paste to backup data (if you don't see it, you have to close the web console or scroll down).
If you want to send direct messages without using Android / iOS and the official proprietary app, you can use open source desktop apps like IG:dm, do cURL requests to the API or use my web browser script instagram-api_send_message.js.
