With Export Feature enabled, you can then enter the channel you wish to export the conversation from, select Channel Menu and click Export conversation as pdf. This will trigger a window that allows you to select the time frame of the conversation you wish to export.
After selecting your time frame, your conversation will automatically download as a pdf file.
