How do I download my theme?

My website is and I’m using the most recent version of ghost, which is 5.70.2
I need to apply some changes to my theme, but I can’t find it in this new UI. Before, I just went to advanced settings, clicked download theme and there it is.
Now, I click on design & branding, costumize, click on “change theme” on the lower right corner, “installed” and my theme is listed, however, there is no download button, as I thought there would be.
anyway, how do I download my theme in this new UI?

Nevermind, just found it out myself lol.
Here’s how though, if someone comes across the same problem (yes it’s teaching how to do with the new UI)
Download and upload a Ghost theme
