Can the _id in my database have the same value as the _owner?

Additional to shimonsuissa1954-advise, you could also manipulate the location where you want to direct to as you want…

Just as little example here…

https://russian-dima.wixsite.com/meinewebsite/create-my-link

This shall just show you, that you can manipulate your url as you want :wink:.

So get the current users-informations…

import wixUsers from 'wix-users';
2
3// ...
4
5let user = wixUsers.currentUser;
6
7let userId = user.id;           // "r5cme-6fem-485j-djre-4844c49"
8let isLoggedIn = user.loggedIn; // true
9
10user.getEmail()
11  .then( (email) => {
12    let userEmail = email;      // "user@something.com"
13  } );
14
15user.getRoles()
16  .then( (roles) => {
17    let firstRole = roles[0];
18    let roleName = firstRole.name;                // "Role Name"
19    let roleDescription = firstRole.description;  // "Role Description"
20  } );
21
22user.getPricingPlans()
23  .then( (pricingPlans) => {
24    let firstPlan = pricingPlans[0];
25    let planName = firstPlan.name;          // "Gold"
26    let startDate = firstPlan.startDate;    // Wed Aug 29 2018 09:39:41 GMT-0500 (Eastern Standard Time)
27    let expiryDate = firstPlan.expiryDate;  // Thu Nov 29 2018 08:39:41 GMT-0400 (Eastern Daylight Time)
28  } );

Choose the data of the user which you need.
Get your location.to …
(/Members/${wixUsers.currentUser.id})
Modify it in similar way like shown in example and do what ever you want with your own generated/manipulated LINK/URL/LOCATION what ever.
