Can workspace be opened when offline?

Hi guys, Can workspace be opened when offline? My situation is when I sign in my account, but I cannot open workspace , may be caused by some network problems(using office network, may be some connetions blocked by firewall because of security or other strategies), so I cannot use Postman totally.

So can we provide a feature that after login the account and get workspace data from server, we can use or modify the APIs locally.
Really hope you can consider that!!!
