`pkgdown`: use hexSticker package logo in navbar (instead of favicon)

Question

In package pkgdown, is there any way to use a hexSticker package logo in the navbar, instead of a favicon logo?

Right now, a _pkgdown.yml file might contain the following code to link to another package:

navbar:
  type: default
  toc: TRUE
  right:
  - text: rempsyc
    href: https://rempsyc.remi-theriault.com/
    aria-label: rempsyc

Using a favicon, we would replace - text: rempsyc with something like - icon: fa-github if we wanted the GitHub logo. I'm wondering if it would be possible instead to use something like:

- icon: favicon\favicon-16x16.png for using the current package logo in the navbar (stored in pkgdown\favicon). And possibly - icon: assets\logo2.png for using another package logo stored in pkgdown\assets. Is this possible?
