Closing a Delaware C-corp that never conducted business

Anyone able to advise on the cheapest way to dissolve a C-corp which was opened through Clerky but which never opened a bank account or conducted any business?

I've seen some folks online recommending to call the registered agent, ask them to resign and delete all records of the company.

Alternative seems to be paying at least $400 in taxes and then $200 for a dissolution certificate. Which is quite a hit given that the business has failed.

Any input would be greatly appreciated.
