To stay updated when your SharePoint documents or items on your site change, you can create alerts. Alerts can be sent to your team via email.
You can get an alert whenever a file, link, or folder is changed in a SharePoint Online document library. Depending on the item (file, folder, link), you may see different options when you set an alert.
Open the document library and hover over the file, link, or folder for which you want to get an alert, and click the check mark.
Click the ellipses (...) to the right of the item name, and then click Alert Me.
In the Alert me when items change dialog, select and change the options you want. For settings and descriptions, see Alert Options below.
Click OK when done.

Click Delete Selected Alerts, and then click OK.
In the Alert me when items change dialog, the following settings are available for alerts on an item, file, link (where supported) or folder.
Note: Not all settings may be available for all alert types or versions of SharePoint.
