Implement Support to "Share" Feature
most of the social apps have “Share” feature.There are two ways. “Share From Mattermost To …” and “Share From … To Mattermost”
Those allow integration between apps and make it easier to add messages and links to Mattermost.
There's another suggestion that seems to be a duplicate (or at the very least, very similar) to this one - https://mattermost.uservoice.com/forums/306457-general/suggestions/31272532-share-pictures-from-the-app
“Share From … To Mattermost” is already supported but it does not seem to be working on android on certain devices.
Also “Share From Mattermost To …” would really be good. The current process is really painful to first download the attachment, then go that app, find the downloaded file & then share. This feature could really help.
