I think you're a bit mistaken. Per https://www.edf-feph.org/enforcement-toolkit-european-parliament-peti-committee/
"The Petitions Committee does not have investigatory nor enforcement powers and it can only adopt non-binding recommendations. Nevertheless, it can be a good tool to draw political attention to specific matters."
At most, it makes the parliament have to look at the proposal and decide if its worth looking into or not. It doesn't force anything.
Unless I'm looking at the wrong kind of petition to the EU Parliament?
As an FYI you can also check on Medicare if you have it linked to MyGov and/or on the Medicare App. (If it works for you). Can even Register to be an organ donor on there if you haven't before.
