If you find an app you think would be useful for others, it's easy to share that app with them.
On the app's page, select the Share icon, then select Share. You can also select Copy link if you want to simply paste a link to the app in a message or post.
Enter the names of the people, groups, and channels you want to share the app with. You can customize the message in the middle if you want. When you're done, select Share.
