Using Zoho Connect Channels vs Zoho Cliq ?

Using Zoho Connect Channels vs Zoho Cliq ?

Hello,

Zoho Connect includes a live chat solution with 'Channels'.
I have some questions about it :

1) Is Cliq really useful if all my team is in Zoho Connect ?

2) What are the differences between Zoho Connect Channels and Zoho Cliq (except the Cliq dedicated platform) ? Does both provide the same features ?

3) If we don't use Cliq, are the Connect Channels included in the Smartchat ?

Thank you for your help.
