please help with decrypting files that are encrypted with .cool encryption with online ID, no key or text file is present so is there any way to decrypt it.
If your files are encrypted with an online key, they cannot be decrypted. There are no other recovery methods other than those described in the article (https://www.myantispyware.com/2019/12/04/how-to-recover-encrypted-files-ransomware-file-recovery/). If the methods described in this article did not help you, then I advise you to back up your important files and wait until decryption becomes possible. This can happen in a year, two years, or even never. Follow the news on our website or in our Facebook/YouTube account.
