[SalesForce] Adding users to the community… need access to the community

I'm doing a tutorial on communities, and after setting pages and themes, i wanted to add users. When i try to setup the user, i get this message: "Looks like this portal user is not a member of a experience".

The access is made from the contact object, so the related user has this configuration:

Profile = Customer Community User
Active = true

when in the community layout, i went to top ledt corner, with my system Administrator user, and all the buttons: Builder, moderation, Administration, take me to a login page. I tried with my user, but the password is invalid, so i guess that means i should either use this community user, or adding my own to that community.

I also seen you can do this adding permission settings, so i activate the ones i could find related:

View Content in Portals
Manage Users
Manage Customer Users

The configured expedience is there, and i can open the builder link
enter image description here

on the top-left button, i can click on Builder, wich takes me to the to where i can edit Themes and pages. That works well

But all the buttons below take to this url:

this be a security risk? well, its a developer org…)

http://[site URL]/darthdaderiscool/login?ec=302&inst=5J&startURL=%2Fdarthvaderiscool%2FcommunitySetup%2FcwApp.app%23/c/page/dashboardManagementHome

site URL = the same i find in the setup > Sites > All sites
darthvaderiscool = url of that community
url parameters = url parameter that follow, i show them bellow (would showing 

7 links, only the first works

All those 6 links take me to this same login page:

login page

I'm using classic, and its a developer org. The result is exacty the same, with classic and Lightning. So, if adding users to a community is done in that Administrator link, and to that i need to access the community, with a community User, this is a circular problem. How can i add any user that user to the community?

Best Answer

Access to a community is based on the assignment of one or more profiles to the community. Any user that is using one of those profiles has access.

Make this assignment by clicking on the "Workspaces" link then on the "Administration" tile then on the "Members" tab, and adding one or more profiles:

Members tab

Note: do not remove the "System Administrator" from the list. If you do, you will not longer be able to modify the community.

Somewhat related, you can also configure the profile that self-registering users are given via the "Login & Registration" tab:

Login & Registration tab

I now add these priveges in a permission set, to my System Administrator User:
