SXA's Local "Data" datasource folder not displayed in the Content Editor for content editors

Question

Some how, the local "Data" folder (the one from SXA), underneath a page, is not displayed for content editors in the Content Editor:

While an admin is able to see it in the Content Editor:

According to the access viewer the content editor should be able to see it:

Is this a "feature" of the SXA local "Data" folder, to prevent users from editing it in the content editor because they should use the Experience Editor?

Answer 1

The local Data folder in SXA is usually hidden.

Check for the other users in the View ribbon tab, if Hidden items checkbox is checked:

Answer 2

While trying to configure security for the users of our system, I found that I needed to grant access to the template used for the Data item; which I believe is a Virtual Page Data.

Example: The following applies security changes to the Data folders.

# This is a helper method to simplify the changes.
function New-AccessRuleList {
    [CmdletBinding()]
    [OutputType("System.Collections.Generic.List[Sitecore.Security.AccessControl.AccessRule]")]
    param(
        [string]$Identity,
        [string[]]$AccessRule,
        [Sitecore.Security.AccessControl.PropagationType]$PropagationType,
        [Sitecore.Security.AccessControl.SecurityPermission]$SecurityPermission
    )

    $list = New-Object "System.Collections.Generic.List[Sitecore.Security.AccessControl.AccessRule]"
    foreach($rule in $accessrule) {
        $list.Add((New-ItemAcl -Identity $Identity -AccessRight $rule -PropagationType $PropagationType -SecurityPermission $SecurityPermission))
    }

    @(,$list)
}

$allowItemProps = @{
    PropagationType = [Sitecore.Security.AccessControl.PropagationType]::Entity
    SecurityPermission = [Sitecore.Security.AccessControl.SecurityPermission]::AllowAccess
}

$realEveryone = "\Everyone"
$virtualDataItem = Get-Item -Path "master:" -ID "{9700DC24-8969-4638-ACC3-34D54335829E}"
$accessRules = New-Object Sitecore.Security.AccessControl.AccessRuleCollection
$accessRules.AddRange((New-AccessRuleList -Identity $realEveryone -AccessRule item:create @allowItemProps))
$virtualDataItem | Add-ItemAcl -AccessRules $accessRules

The final results:
