Paramount Plus with Showtime

I was informed via chat that I have access to Paramount Plus. However, I already pay a lot for Xfinity, and if this issue isn’t resolved, it may be a deal breaker for me. Other options are simply more reasonable. 

I would like clear and accurate information. During the chat, I was instructed to visit the website paramountplus.com/activation, select "Connect Provider," enter the code displayed on my TV, and then choose Xfinity. However, I don't see Xfinity listed as an option.

I am confused and feel like I’m being given the runaround. Is Xfinity actually a connected provider? If so, please provide the correct information. If not, please let me know. Thank you.
