We should ensure that every links has an accessible name, including the logo link in the navbar that doesn't provide any label. The chosen solution to fix this issue is the following:

ARIA14: Using aria-label to provide an invisible label where a visible label cannot be used [1]
> In some situations, elements can be given the attribute aria-label to provide an accessible name for situations when there is no visible label due to a chosen design approach or layout but the context and visual appearance of the control make its purpose clear.
