Mere paas windows 10 nahi hai ab, so video nahi bana sakta hun. microsoft ka page hai ise ek baar dekhiye - learn.microsoft.com/en-us/windows/wsl/install
not working getting 403 ☹☹, though i am able to open file using link in browser but not from react or simple html page, is something updated?
As I know nothing updated, when you are opening from browser that is different, and when using it from application then its different. Is drive directory is public ?
@@codebyheart yes it is public and got it working with drive.google.com/thumbnail?id= this link, but the mentioned in the video not working for me 🫤
