The design belongs to someone else. Copying another brand's ad with its images, wording or logo is not a template; it is their work. Use it as a layout reference and build your version from your own material.
It is a website or app screen. Interfaces need vector shapes, auto layout and live text. Figma's own screenshot-to-design feature (in beta on paid plans) and similar tools rebuild screens as editable frames; a layer splitter returns pictures.
The design is mostly text. A carousel slide that is nine lines of copy on a colour is faster to retype than to split.
You still have the original file. Open it; nothing rebuilt from an export is better.
