ESTABLISHING NEW CONNECTIONS IN A COMMUNICATION PLATFORM

Techniques for enabling contact sharing via communications transmitted via a communication platform are described herein. In an example, a first user can communicate with a second user via a virtual space (e.g., direct messaging instance, communication channel, etc.) of the communication platform. The first user can include an indicator associated with a third user in a communication to be transmitted via the virtual space. In response to a determination that the second user and the third user have not previously established a connection, the communication platform can associate a contact card of the third user with the communication. The contact card can include contact information associated with the third user. The contact card can be selectable to enable communications between the second user and the third user and/or to add the contact information associated with the third user to a contact list of the second user.
