How to mark record in creatio readonly on particular condition

I want to make a record read-only for all users in Creatio based on a condition.

I have added a checkbox field on the record. When this checkbox is checked, I want the entire record to become read-only for all users.

To achieve this, I created a Business Process that modifies access rights for the record when the checkbox is updated. The process runs successfully without any errors. However, the changes are not getting reflected on the UI users are still able to edit the record.

Could you please help me understand:

• Is modifying access rights via Business Process the correct approach for making a record read-only?
• Are there any additional steps required to enforce read-only behavior on the UI?

Any guidance or best practices would be greatly appreciated.
