Reimbursement for video consultation with a Doctor based in EU but outside France when I was actually in France?

During the weekend, I was sick and was able to get a video consultation with a doctor through Mobidoctor, a website connecting me to doctors in the EU. I was at that time at home in France, I was not abroad myself. The doctor was based in Portugal, but the Mobidoctor website is set up in Malta. I was diagnosed with sinusitis (sinusite) and given a prescription for medication, which I took to the local pharmacy here in France. At the pharmacy, the pharmacist said she couldn't submit the ordonnance for reimbursement from social security but gave me a feuille de soins.
My question is, how should I submit the feuille de soins for the prescription and the reimbursement certificate/bill from the video consultation from Mobidoctor to CPAM - the online submission is only for reimbursements while outside of France, while I was actually in France when I did the consultation and filled the prescription. Do I use the online form anyways? Or do I need to send the documents by the post (paper copies)? I don't see my situation reflected in the FAQs.
My mutuelle advised that I need to submit the paperwork to the CPAM before they will look at reimbursing me.
