@brenoalvs thanks for informing.

I would like to know if you want to push the generated pot file to the open pull request or you want to generate the pot file once the pull request is merged ?

@varunsridharan Hm, I think that makes sense push on the PR branch.
If developers want to generate the POT file after merge they can use the push event instead which is triggered when a merge occurs.

[varunsridharan]

@brenoalvs so what I understood is that you want to trigger this action when a pull request is updated & push the generated pot file to the pull request branch ?

@varunsridharan Correct
