Ask the extension to add a new connection to the chain of the given name.
The substrate-connect extension comes with some hardcoded chain names that applications can
connect to. This list of names isn't indicated here, as it can change over time.
Because the extension reserves the right to remove support for a well-known chain in the future,
applications should fall back to ToExtensionAddChain if this well-known chain
connection fails.
Identifier for this chain used in all future messages concerning this chain. Allocated by
the sender of this message. It is recommended to generate this ID randomly, with at least
48 bits of entropy.
