@Namanv0509 Can I work on this issue ??

[aryanG9403]

Hi! I'd like to work on this issue as well.

I have JavaScript experience and my dev environment is already set up and running. I can implement both the ESC key handler and double-click exit functionality.
I'm active in the Layer5 Slack and can start on this immediately.

Could you please assign this to me?

Thanks!
