Is there an alternative to window.open in Adobe CEP?

Hello Adobe Community,

I hope you're all doing well. I am currently working on a Creative Extensibility Platform (CEP) project and facing a specific challenge related to the use of window.open in my extension.

My CEP extension involves implementing Single Sign-On (SSO) authentication. The SSO flow requires opening an external authentication page, and I initially attempted to use window.open for this purpose. However, I discovered that window.open is not supported within the CEP environment due to security restrictions.

I am now looking for an alternative approach to achieve the SSO authentication flow within the CEP extension. Here's a brief overview of my intended flow:

1. The user clicks a "Login" button within the CEP extension.
2. This should trigger the SSO authentication process, which involves navigating to an external authentication page for login.
3. Upon successful login, the user is redirected back to my extension with necessary authentication data (e.g., User_ID).
4. I need to retrieve the authentication data from the response and use it within my CEP extension.

I would greatly appreciate any insights or suggestions on how I can implement this SSO authentication flow effectively within the constraints of the Adobe CEP environment. If there is an alternative to window.open that would work in this context, or if there are any workarounds, I would be grateful to learn about them.

Thank you all in advance for your time and expertise. I'm looking forward to hearing your valuable feedback.
