Hi @Lilo2, let me see if I can help out here!
In which app have you deleted the photos, in the Album app or in Google Photos? I am afraid that the only app that has a recycle bin where deleted photos end up ens up is Google Photos. If you accidentally deleted photos in Google photos, try opening the app > Tap the three horizontal lines in the top left corner > Tap "Bin". From there you should be able to find and restore deleted photos.
I hope that helped!
