How to lock a record to prevent multiple users working on the same transaction record

Summary:

Lock a record to prevent another user is opening the same transaction record.

Show a popup stating another person is already working on the same transaction.

Release the lock if a person closes the transaction record.

Content (required):

We have a custom Visual Builder application where users can open transaction records from a table on their homepage.

When opening this transaction, they are in an 'edit' modus where they can make adjustments and save or submit the transaction.

However, multiple users can open the same transaction record at the same time.

Is there a way to 'lock' a record in the Visual Builder application if someone is working on a transaction, to prevent another user is opening the same transaction record?
