Upgrade to Logic Pro X 10.7.2

I am an existing Logic user.

Logic Pro is available as a single version for all customers.

At this moment I have Logic Pro X 10.4.6

It does not work with

Mac OS Monterey v 12.1

The Logic Pro X 10.4.6 can not open.

How can I update Logic Pro X 10.4.6

To

Logic Pro X 10.7.2

For free?
