Using my own Buttons

I’ve created a title page using the Unity UI to create buttons for Start and Help. The Unity buttons look pretty plain and I want to replace them with my own, but still using the Unity button inspector and the script I’ve attached to it to change the scene. I can’t find a way to do this, though I’m sure it must be possible. Can anyone help please?

Can’t you simply change the sprite for the button? Or what exactly is the issue?

Thank you Mikael-juhala. I didn’t realise I could simply change the sprite. I have now and it looks good. Thanks again
