Delete photos from Mac?

I recently got a MacBook Pro and of course after a while I wanted photos for my background too.

Since I don't have a camera, I used a trick by sending the desired image from my Huawei phone to my Mac.

There was a picture that I find quite annoying in my 'gallery' and I would like to delete it. However, there's no right button and left button on my Magic Mouse, just one. How can I delete this picture? I've tried a lot, but I can only edit the image (colors, tones, …) and drag it around, but not to the trash. All the help on the Internet did not help me, as I'm not familiar with the keyboard on my Mac (which by the way looks completely different from normal keyboards): /

I hope someone can help me and sorry for the long text 😅
