How to customize the label on tag

[alexgurman]

Log.txt
Trying to customize the label a bit, so instead of specifying just build.buildNumber it would also add a static string - like 'Deployed by Octopus Deploy - build.buildNumber'

So I specified in ADO build:
- task: git-tag-on-release-task@9
inputs:
replacePattern: 'Deployed by Octopus Deploy'

And the result was the same as without any parameters, just the build.buildNumber.

What am I doing wrong? Attached is the log from run with system diagnostic enabled
