People Picker in Microsoft Project Online

Solution for People Picker in Microsoft Project Online
is Given Below:

I am looking for a way to add people picker to Project Online, like the Owner field on the Project Information form. But I want to display all the users from my organizations AD (Office 365 users).

Many articles and SO questions are pointing to this link, , however this link is no longer pointing to any useful resource.

There is no option to add this via Custom Fields in Project online. There is a uservoice feature request created in 2018 but seems like MS did not implement such a common feature.

Any guidance is really appreciated
