@turbolent thanks for the feedback!! I should have avoided that mistake since the templete was already included in the PR but I wasn't sure on how to filling it out. I'm gonna ask for some help to my big sib @joshuahannan and get the PR properly done. Please apologize for the inconvenience I guess I'm still getting familiarized with the workflow.
