I have issue on create storage path for access main domain file from sub domain project. main domain - https://etest.com sub domain - https://recovey-test.com
Files will uploaded to recovey-test.com by API and need to show those files in https://etest.com admin panel.
In your subdomain project you could create a new "disk" in config/filesystem.php :
],
You should do then all file operations through this disk. Hope I got your question right and this helps.
