I think it would be better to make this PR against master. We're only making bug fixes on the 7.2 branch.

Hi Matthew,

Thank you for your time and consideration!

It would be great to add information about the plugin to the master branch.

Also, we would like to note that we opened an issue with the same purpose, therefore, this pull request and the issue can be considered equivalent.

Grateful for your help!

Hi Matthew!

Is it necessary to sign the CLA to add our plugin to the list?

A new PR was opened and merged against the master branch. As such, I am going to close this. #41655
