Deleting and creating the Domain Group “Everyone” in Sharepoint 2013 using Powershell CSOM

Question

With Powershell CSOM and SharePoint 2013, I am trying to reset the permission to the domain group "Everyone", with the name "c:0(.s|true". Therefore I want to delete and recreate it, so that all the permissions "Everyone" has gotten over time have been reset.

What is the correct Powershell CSOM code for executing these actions?

I also want to do the same for the group "Everyone except external users", but I suspect it's the same procedure as to the question above.

EDIT: I'm also satisfied with a way to iterate through the permissions and removing them one by one. What is the Powershell CSOM command for removing a groups permission to a list?

EDIT2: I'll supply the code that I've currently built the last hour. I'm getting an error in the line:

$list.RoleAssignments.Remove($group,$roleAssignment)

Error: An error occurred while enumerating through a collection: The collection has no t been initialized. It has not been requested or the request has not been execu ted. It may need to be explicitly requested.

Code:

$permissions = $Context.Web.RoleDefinitions
$Context.Load($permissions)
$Context.ExecuteQuery()

$lists = $Context.Web.Lists
$Context.Load($lists)
$Context.ExecuteQuery()

$group = $Context.Site.RootWeb.EnsureUser("c:o(.s|true")
$Context.Load($group)
$Context.ExecuteQuery()

foreach ($list in $lists)
{
    $list.BreakRoleInheritance($false, $true)
    foreach ($permission in $permissions){
         $roleAssignment = $null
         $roleAssignment = New-Object Microsoft.SharePoint.Client.RoleDefinitionBindingCollection($Context)
         $roleAssignment.Add($permission)
         $list.RoleAssignments.Remove($group,$roleAssignment)
         $Context.ExecuteQuery()
     }
}

Here's something to start with in C#:

$lists = $ctx.Web.Lists
$ctx.Load($Lists)
$ctx.ExecuteQuery()

foreach($list in $lists) {    
    $ras = $list.RoleAssignments
    $ctx.Load($ras)
    $ctx.ExecuteQuery()
    foreach($ra in $ras) {        
        $ctx.Load($ra)
        $ctx.ExecuteQuery()
        if ($ra.PrincipalId -eq $everoneUserId) {
            $ra.DeleteObject();
            $ctx.ExecuteQuery();
        }
    }
}

That should do the job. It's been awhile since I've used PowerShell, so there might be some issues.
