Create a PR automatically when the import Github Action is run

[emmambd]

What problem is your feature request trying to solve? Right now after the Github action is run, we have to

• Go to the new branch
• Create a new PR

Describe the solution you'd like Would be more convenient if a PR is just automatically created upon running the Github action.

How will we know when this is done? A PR is automatically generated when the Github action runs

@emmambd I think so. Should be done by Monday.
