Renew GUID via API?

In an attempt to automate my podlove instance at anerzaehlt.net I wrote a plugin that randomly republishes old episodes. Some people complain to me that they do not see the reposted episodes because they already listened to it in the past. Hence my question: Is there a way to renew the GUID via API? I was not able to figure it out and appreciate any pointer. Thank you!

Is that a “nope, not possible”?

You need to use the WordPress REST API to set the “post meta” _podlove_guid to a new value. That should work.
