Hi,
This message comes from https://github.com/JetBrains/intellij-community/blob/241/platform/vcs-impl/src/com/intellij/vcs/commit/CommitProgressPanel.kt#L229
It doesn't seem possible to add custom messages here.
BTW, you can use UI Inspector to find the code behind UI elements: https://plugins.jetbrains.com/docs/intellij/internal-ui-inspector.html
Thank you for your help.
