How can students add collaborators to their Google Doc?

Adding collaborators to a Google Doc is accomplished through the blue "share" button, which is prominently located in the upper right corner of the document interface. When users click this button, a sharing dialog appears, allowing them to enter the email addresses of the individuals they wish to collaborate with. Additionally, this dialog provides options for defining the permissions of the collaborators, such as whether they can edit, comment, or only view the document. This feature is central to the collaborative functionality of Google Docs, enabling real-time editing and teamwork.

While sending an email invitation, copying the document link, and using Google Meet calls may facilitate communication or sharing, they do not directly utilize the built-in collaboration features offered through the “share” button. The blue "share" button is purposefully designed for adding collaborators efficiently and effectively, making it the most appropriate choice in this context.
