No problem … however, have you installed “kio-gdrive”??
You will need that. So, if you haven’t, install via Yast / Myrlyn or
# zypper in kio-gdrive
An additional file will also be installed.
Next, go to KDE System Settings → Online Accounts. Then click on “Add New Account”, then select Google option.
Afterwards, open the Dolphin file manager, and check the left-hand panel (Network) - should see Google Drive.
