How to use with delve

I'm not sure if I'm using this package with delve properly. Here's my current flow

1) run `gotestsum --watch`
2) press 'd' to have the test run with delve
3) work through the breakpoints (e.g. by just pressing 'c')
4) observe that test fails
5) delve prints `Process 51458 has exited with status 1`
6) I get to the dlv prompt again but I'm not sure how to actually restart the test now without exiting and running `gotestsum --watch` again.

Is there something I need to run to get the test to restart without killing the session?

Thanks!

Start by reproducing the listed `gotestsum --watch` and delve flow, then inspect the command handling around the `d` action and the post-exit prompt. Determine whether the test can be restarted in the existing session; done means documenting the supported restart procedure or clearly stating that the session must be restarted.
