There are still two issues on the pull request that need to be addressed before it is ready for review:

1. The tangle-substrate-types package needs to be published with the fixes from PR https://github.com/webb-tools/tangle/pull/572. Currently, it is using the local package.
2. There is a testing error with jest: Jest has detected the following 1 open handle potentially preventing Jest from exiting.
