Extending the default restoration time period in SharePoint Online more than 14 days
The info you've read most probably concerned the Exchange Online single-item recovery window, it's not applicable to SharePoint Online. The restoration process is entirely driven via support requests, we dont have any options to control it.
The self-service options are detailed in the information Cian Allner posted above.
To add to Vasil's point, the default retention time for deleted items is 14 days in Exchange Online. You can amend this to a maximum of 30 days:
Set-Mailbox -Id "Some Mailbox" -RetainDeletedItemsFor 30
You can also use the Set-MailboxPlan cmdlet to change the default from 14 days to anything up to 30 days.
This setting controls the time deleted items spend in the Recoverable Items folder before they are permanently removed from the database (unless on hold).
TonyRedmond....Thanks for the update
