External Access Policy - CsExternalAccessPolicy e CsTenantFederationConfiguration (PowerShell)

Hello, community.

We are trying to enable functionality regarding the creation of external access policies using the New-CsExternalAccessPolicy (CommunicationWithExternalOrgs) and Set-CsTenantFederationConfiguration (CustomizeFederation) commands. However, we are receiving the following error:

Set-CsTenantFederationConfiguration : Customize Federation is not allowed to enable in your tenant. In line:1 character:1 + Set-CsTenantFederationConfiguration -CustomizeFederation $true + ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ~~~~~~~~~~~~~ + CategoryInfo : InvalidOperation: ({ ConfigType = ...Configuration }:<>f__AnonymousType104`5) [Set-CsTenantFederationConfiguration], Exception + FullyQualifiedErrorId : ClientError,Microsoft.Teams.ConfigApi.Cmdlets.SetCsTenantFederationConfiguration

Is it necessary to do something first? We are following the documentation below:

TKS!
