In Developer Tools > Network > XHR
For new JavaScript fetch requests :
Right click on the request made, mouse over "Copy", click "Copy as fetch".
Go to Developer Tools > Console
Paste the copied information
Press "Enter"
To re-replay, simply go to Console, press "Up" and "Enter"
Otherwise, I've read that for other requests, made by Axios, for instance can be replayed by :
Right click on the request made and click "Replay XHR".
I've also read that there are other solutions, but you got 2 now.
