Is there a way to download all of the games I had ever played on the site?

Hi, I haven't used this feature of the website ever before. I just thought it was a standard option. I wanted to search for certain positions and openings I had encountered from among my games which I've been playing since 2015. When I go to section of "My games" on the site, it does allow to download a PGN, but it looks like it only lets me download 50 games at one time. 

Does anybody know where and how I can select to download a PGN file with all of my games. I do not know yet what filter criteria I would use. For example, all of my slow games as on PGN, another with my 5 minute games. 

Is there a way to download all at once?

Thanks!

Can anybody please help?

If you're good at programming, you can use the Public API to do it.

I believe there are some members have written scripts to do it as well, but I've never looked at any so can't recommend anything.
