Generate email QR code for iOS15 with body and subject

On iOS 14 I am using this format to get QR code correctly recognised and subject + body transferred to new email message: mailto:__@_?subject=Hello&body On iOS 15 this doesn't work.

Is there a new format to use?

mailto:__@_?subject=Hello&body=11 (Accidentally missed the body)
