Custom Slider + Slide Number

Hey guys, super new to Webflow - currently stuck on this, looking to create a custom slider for text with one right arrow (carousel effect) as the slide number changes for the respective slides when the user clicks the arrow. [and a button in the bottom corner]

Attached the image, let me know what I should do or if I’m on the right track! Thank you

Also looking for a solution to this. I want the slider to move 3 slides per click.
