convertGroupTMRTemporaryKey method

void convertGroupTMRTemporaryKey(String groupId, String temporaryKeyId, String tmrJWT, Uint8List rawOverEncryptionKey, { bool deleteOnConvert = false, })

Convert a group TMR temporary key to become a group member.

groupId The Id of the group for which to convert a TMR key. temporaryKeyId The Id of the temporary key to convert. tmrJWT TMR JWT to use. rawOverEncryptionKey The raw encryption key to use. This MUST be a cryptographically random buffer of 64 bytes. deleteOnConvert Should the key be deleted after conversion.
