Running two instances on same laptop

I'm trying to run two instances of cabal on the same laptop, but the second one crashes:

npx cabal cabal://628d1d75d1197fe05c650fb6b2d5a90171adb1185c0d89772db758b93803b94b?admin=d431586157ba4ed341883c41054c1a5779388236fe8e4c2736d10f7d2191efa1

      return callback(new OpenError(err))

Node.js v20.11.0

When I stop the first one and retry the second one, it succeeds. Is there a way to tell cabal not to use this default global resource?

Ah, found it! Running both instances with npx cabal --temp cabal://628d1d75d1197fe05c650fb6b2d5a90171adb1185c0d89772db758b93803b94b?admin=d431586157ba4ed341883c41054c1a5779388236fe8e4c2736d10f7d2191efa1 works for this, now I can /join default in both terminal windows and the two can chat with each other.
