I noticed that the Github repository for this plugin does not have dependabot enabled.  Almost all other Jenkins plugins have dependabot enabled to get automatic updates for plugin dependencies.

See for example:

https://github.com/jenkinsci/s3-plugin/pull/136/files

https://github.com/jenkinsci/credentials-plugin/tree/master/.github

https://github.com/jenkinsci/conventional-commits-plugin/tree/main/.github
