Adding users to group DM should provide an option to keep history
When you have a multi user direct message and you add new members (as a conversation grows to need more people) you end up creating a new DM with no history. Instead mattermost should provide an option to keep the history available.

This would be really needed feature, if not yet added.

Please add this option. We very frequently have cross-team collaboration and it's really jarring to bring another user into a Group DM for additional input and have the chat history disappear.
More than a year and nothing happened with this? How many votes are needed to move this up?

An alternative is to convert the direct message to a private chat but this is not available without being a Team Leader or Administrator.
This is very frustrating. The new users should be able to see the history—I'm bringing them into the conversation for a good reason. There is no security risk here.
These workarounds did not work to show the new user the message history:
• the new Firefox scrolling web page screenshot tool cannot scroll the page
• neither can the Chrome Awesome Screenshot
• neither can the Snag It tool
• neither can the macOS print to PDF tool
• there is no way to export a chat
The only way that works is to copy and paste...and we are unfortunately still using MM 4.x, which has a 4000 character limit. Sigh. So frustrating.
