How to receive an event when opening a project in AfterEffects

[YuK1_Works]

Is there a way to receive a CSEvent when a project is opened in AfterEffects?
https://github.com/Adobe-CEP/CEP-Resources/blob/master/CEP_11.x/Documentation/CEP%2011.1%20HTML%20Ex...

It seems that the documentAfterActivate and documentAfterDeactivate shown on this page are not received by AfterEffects.

I am using machine translation, so if you have any difficulties in understanding, please ask.

Thank you.

Unfortunately, After Effects doesn't provide such events.

i don't know about CEP, but you can periodically check the current project name and path, and when it changes from the last call you can deduce a new project was opened.

That's not a good practice that will lead to performance issues after a while.
