Can I use the 'SAML2 WEB APP' add-on when creating a 'Regular Web Application' in a B to C plan?

Hello everyone, I hope you’re all doing well. I have a question about B to C plan agreements that I was hoping someone could help with. Specifically, I’m wondering if it’s possible to use the ‘SAML2 WEB APP’ add-on when creating a ‘Regular Web Application’ under this plan. Any advice or insights would be greatly appreciated. Thanks in advance for your help!
