One external HDD used by High-Sierra and Mojave

[Gwin]

Hi all kindness guys. I upgraded my iMac-2012 from High-Sierra to Mojave yesterday. Before upgrading, Backing-up High-Sierra system with Time Machine (TM) had been done and Mojave was installed on my machine successfully. I have just backed-up a new system using TM (same external hdd). Now, I want to get some desktop files from TM which backed-up in High-Sierra version but I can't see any previous backup files in TM. Could you tell me how to show or access to those files in Time Machine's time line. Any help is appreciated.

Try holding down the option key then click the TM icon in the menu and select "Browse other disks" and see if that will let you select the other backup set.
