Suggested change

	# Only use the import statement, if you want to import an existing logs instance
	# Only use the import statement, if you want to import an existing logs access token

Please add here also an hint, that the actual access token will not be imported because it can be only read during the creation and that probably lifetime needs to be added to ignore_changes.
Similar like for example in the server resource:

terraform-provider-stackit/docs/resources/server.md

Lines 381 to 388 in d772e2e

	# Only use the import statement, if you want to import an existing server
	# Note: There will be a conflict which needs to be resolved manually.
	# Must set a configuration value for the boot_volume.source_type and boot_volume.source_id attribute as the provider has marked it as required.
	# Since those attributes are not fetched in general from the API call, after adding them this would replace your server resource after an terraform apply.
	# In order to prevent this you need to add:
	# lifecycle {
	# ignore_changes = [ boot_volume ]
	# }
