PowePoint 365 says it only supports WAV audio (self.techsupport)

I recorded some voice clips for my presentation with Microsoft's Voice Recorder app, but when i tried to insert the audio files into my presentation, PowerPoint claims it only supports WAV format, (despite Microsoft's own website claiming it also supports m4a).

Which is an issue because i need to upload the .PPTX file into my university platform that supports 20MB per file max. (The presentation weights 60MB with the WAV-converted files).
