Restrict one page per user

Hi

I am looking for a solution to password protect/restrict access of 1 or more pages to only 1 user.

Is this possible with your plugin?

I tried adding a user or one page, but it didn’t work on the front end, https://www.screencast.com/t/A0UbNwul4U there appeared to no restriction.

I want it so each of my clients can view a specific gallery page I have created for them.

Many thanks in advance
