How to embed an audio recording of the newsletter

Hi, we would like to include an audio recording (of the newsletter) into the newsletter. The audio is on an mp3 format but so far i haven’t been able to find a solution to include it properly.
To have a format similar to what substack does with the audio recording of the content.
Is it a possibility at that stage or what would be the best way to proceed?
thank you in advance for you help!
Best,

actually - i was able to include an html with the link of the recording. However, when i sent a test to myself, the recording disappear. Is there a way to keep it into the newsletter? thank you!

Hi @Mariealixmotte , did you find a solution in the end?
