Problems to include links to other formats

[Ppantaleo]

Description

Hi, I have been able to include other links, but I cannot enable links to the other formats. I have, in addition to HTML, ePub and PDF, but they are not displayed. what should I improve? Thank you.

Repo is here: https://github.com/PaideiaPublishingServices/Paideia-Editorial/blob/main/Editar%2C%20publicar%20y%20financiar%20ciencia%20en%20Am%C3%A9rica%20Latina/_quarto.yml

Did you look at the documentation?
https://quarto.org/docs/output-formats/html-multi-format.html

Note that I don't think Book is supported at least not this way, see sidebar tools: https://quarto.org/docs/books/book-output.html#sidebar-tools

Thanks, downloads: [pdf, epub] seems to work. If not, you still have to use other-links, right?

Download should work with all book supported formats.
