How to increase the number of photos in private messages

Hello, tell me how I can increase the number of attached files in private messages.
Default value 1

Sorry, there’s no simple way to change this in the current version (the number of files is limited to 1 per message), but we plan to improve this in the upcoming updates.

Tell us about the difficult way

I’m looking forward to your answer

This would require customizations in the Messages functionality, unfortunately there’s no simple guidance or a code snippet to add support for multiple attachments in the current version, but this feature has a high priority so it’ll be added to the next Messages update.
