Referencing this document: https://docs.microsoft.com/en-us/exchange/hybrid-deployment/set-up-modern-hybrid-public-folders which I have been told is applicable to Exchange 2016 also. I am confused on these steps as i have found them not to work, so maybe I am doing something wrong so et me break down what I am doing step by step

I download the script listed in that document and place if on my exchange server:

Sync-MailPublicFolders.ps1

I then run Sync-MailPublicFolders.ps1 -Credential (Get-Credential) -CsvSummaryFile:sync_summary.csv

I then go to Exchange online powershell and run

Set-OrganizationConfig -PublicFoldersEnabled Remote -RemotePublicFolderMailboxes PFMailbox1,PFMailbox2,PFMailbox3

where PFmailbox is the name of the mailboxes on-premise

this results in absolutely nothing happening..

It seems good but it can take a couple of hours.

If you connect from an external network, make sure MAPI/http is configured and published correctly. The Autodiscover process from your Exchange Online organization will "find" the on-premises public folder mailboxes you configured in the Exchange Online Set-OrganizationConfig.

If you are using alternate login id, which means your UPN is not your primary smtp address, make sure modern authentication is enabled in Exchange Online for accessing public folders in your hybrid environment.
