Arduino Lint has suggestions for possible improvements to https://gitlab.com/iridium/9704_launch_pad/arduino_library:

Linting library in arduino_library
INFO: No header file found matching library name (Iridium_9704_Launch_Pad.h). Best practices are for primary header     
      filename to match library name.

Your submission has now been accepted! Thanks for your contribution to the Arduino Library Manager index.

The library(s) will be available for installation via Library Manager within a day's time.

You can check the logs from the Library Manager indexer for your library(s) here:

@ArduinoBot check again?

Hello @IRDMPE. The automated system here only operates on open pull requests. Since your submission was already accepted and the pull request merged, the bot won't pay any more attention to this pull request.

If you like the checks that were performed by the automated system when you submitted your library here, you might consider setting up your library repository to do the same. This could run on every commit and pull request to ensure such violations are caught immediately.

Arduino provides a GitHub Actions action that makes this very easy to do by adding a simple YAML file to the repository:

https://github.com/arduino/arduino-lint-action#readme

This action uses the same Arduino Lint tool as the Library Manager system.

It is in use in all the official Arduino library repositories (example).
