How to set lazygit to pass message when merging branches

Hi, first time lazygit user here. I do apologize if this isn't the right label for my question as i don't know whether this is a bug or me thing...

What am I trying to achieve ... `git merge develop -m` so that I can pass a message so that I have meaningful merge.
This is what I have in the `config.yml` for lazy
```yaml
git:
merging:
manualCommit: false
args: "-m"
```

Now when I press `M` `m - regular merge` to merge develop into some branch nothing happens.

The lazy log, rather the command log section shows `git merge --no-edit -m develop` ....
I even tried to set `manualCommit: true` and I get the same command logged.

How can I set lazygit to do the `git merge develop -m` ? and to open the commit or message popup...

Thanks...
