"Read More" Button for Peak Site Library Theme

Is that the Blog Latest Post section on the front page ?

No, On the individual single post at the bottom there is a recent post section with an arrow, photo, and post title to left and 2nd one point arrow to right such as on the "Learn how trade cryptocurrency safely" example post. TIA

Aah thats the Post Pagination - theres a Block Element Type for that, which inlcudes some pre-built layouts:

Legend! Thank you heaps for that! All sorted now!

Glad to be of help!
