Hello @manthan
Sure, you can do
const itemVersion = await client.itemVersions.find(entity.meta.current_version);
To fetch the current last edited version of the record.
Then, you can have access to itemVersion.relationships.editor
keeping in mind that itemVersion.relationships.editor can be the ID of an API token (resolvable through client.accessTokens.find(accessTokenId))
Or a collaborator ID (resolvable through client.users.find(userId))
Depending on who made the last change to the record (a user through the dashboard, or someone through the API using an API token)
Let me know if this works
