Sharing and an removing a user from a shared secret using the API

We need to do some automation so that we can share secrets with users and also remove users from already shared secret.

Looking at the documentation I find very confusing on how to do it.

First, the request example in the documentation has a lot of information that I don't understand why it's there. https://www.zoho.com/vault/api/#sharing-secrets-with-a-user

Why do I need send the secret data like the password and username, or custom columns, etc,,? I just whant to share an existing secret.

And what are all those fields that need to be sent, like, what is the accesssctrlconfigured? or the displayaccctrlicon? etc..

Theres is no explanation in the documentation. Do I need to send just just some information? what are the mandatory fields?

And how do I remove a user from a shared secret? Is using this endpoint? https://www.zoho.com/vault/api/#update-user-sharing-details-for-secret

But what do I put on the request? the example is not self-explanatory.

"logonusers" : JSONArray,
"viewusers" : JSONArray,
"modifyusers" : JSONArray,
"manageusers" : JSONArray

What do I send in all these when I just to remove a user from a secret??
