@grb
I tried your suggestion and it not works because it told me
At least one member or group must have can manage permission.
But I change the steps and it works.
The steps are as follows:
I can go to organizations admin console , members , find me and click, Edit member me, Collections , click cross icon to Remove collection, Save.
Then the collection has no collection owner, if I want to manage it, I can temporarily give myself permissions to manage collection.
@grb Your answer helps me a lot. Thanks a lot.
