Describe the solution you'd like

Currently the domain in the SIWE plugin is hard-coded, which restricts the use of it to one domain at a time (it does work with multiple domains, but it gives an ugly metamask warning). Would like to pass a function to domain when initializing siwe() that can take the context of the request to decide on the domain to use
