Please advise me how to free up the storage taken up by

My MacBook Pro runs macOS Catalina 10.15.4. The storage is 128 GB and now it has only 17GB. But I noticed that there are nearly 25Gb space is taken up by 'Other'. Please advise me how to free up that space to be used. I cleaned caches and Viber images but not a big support. ;-(

I prefer a method without using other expensive third-party apps.

Thank you very much in advance.
