Using Classic Outlook on Windows for personal email, calendar, and contact management
Instead of sending it to you, ask a colleague to save the calendar item as an ics to a shared folder or thumb drive.
They do this by opening the calendar item (event or series) and then choose Save As from the File menu.
Ask them to save it to a location that you can access. If you don't have a shared drive, save the item to a thumb drive.
From your device, go to the calendar and select File, then select Open and Export, and then choose the Import/Export button.
Choose the action to Import an iCalendar(.ics) or vCalendar file (.vcs) > Next, navigate to the location of the saved .ics,
Select the file and then click to Open. If asked, choose to Import.
