How do I update my Fork repository to the latest master repository using GitHub for Windows?

Question

GitHub

The essence of the question is as follows:
A fork of one repository was made, then using GitHub for Windows, the project was cloned to the computer, changes were made and sent to the main project.
Basically the repository changes are accepted along with other changes from other developers. Everything seems to be ok.
There is a need for all changes to be loaded into my fork.
Tell me how this can be done using the same GitHub for Windows? (I understand that I need to learn git commands, but still)
You can of course demolish your fork every time and upload a new one. But...
