Carousel accessibility best practices

I am trying to design a new carousel component but struggling to figure out any accessibility best practices.

These are some of the things I am trying to think about:

Pagination indicators

  1. Should these be clickable
  2. If clickable to they have to meet minimum touch target areas (44px), or if there is another form of pagination such as icon buttons with arrows does this not matter?

Responsive design

  1. Should my designs / interactions for WEB and APPS differ?

If anyone has any knowledge around best practices I would appreciate it!
