iCloud - Delete ALL Inbox Emails AT ONCE in iCloud on a PC / Computer ?

This is 2024. Things change from year to year in software "updates". All advice that I've read so far on how to do this is outdated and does not apply. N/A

Edit/Update: Solution found. And the only solution.

NOTE: @ PC/iCloud/inbox/Settings(gear icon): at this date and time, settings only has options to delete all mail from the Trash Folder or delete all mail from the Junk Folder. There is NO option to delete all mail from the inbox folder.

In your inbox folder click on the top piece of mail to highlight it. Hold down Shift (NOT Ctrl as per usual on Windows to select multiple files) and scroll all the way to the bottom of the mail list while holding down Shift and click on the very last piece of mail in the inbox folder. This will highlight the whole "range" of mail from the first highlighted piece to the last highlighted piece. Then either look in the right mail view pane and you will see "Trash" or right click on the mouse and select "Trash". Done. All mail in the entire inbox folder deleted all at once.
