workflow purge in AEM cloud

Hi All,

I have to purge workflow on AEM CLOUD of more than 10 days older,

I have followed the below article.

https://experienceleague.adobe.com/docs/experience-manager-cloud-service/content/sites/administering/workflows-administering.html?lang=en

 Created config name - com.adobe.granite.workflow.purge.Scheduler.cfg.json 

and the path  of config is -  >   ui.config/src/main/content/jcr_root/apps/wknd/osgiconfig/config.author

{
  "scheduledpurge.name":"Dam Purge",
  "scheduledpurge.daysold:Integer":10,
  "scheduledpurge.modelIds":[
    " /conf/global/settings/workflow/models/dam/update_asset/jcr:content/model"
  ]
}

Please find the qn below : 

1: is the config name correct? 

2.  is the config path (ui.config/src/main/content/jcr_root/apps/wknd/osgiconfig/config.author) correct?

3 is the scheduledpurge.modelIds path is correct?

I have given scheduledpurge.modelIds -- /conf/global/settings/workflow/models/dam/update_asset/jcr:content/model but there is no model present inside our conf folder. Bcz we are using out the  box model . so what should be modelId  for that?

should i have used this model id  form libs  -   /libs/settings/workflow/models/dam/dynamic-media-reupload

because i want to purge this model  dynamic-media-reupload work flow
