Hello!
I just want to know if it even possible modify this menu:
Because we need a navigation tag (role=”navigation” ) or something similar and more accesibility control, but we don't find anything.

You cannot modify this menu directly. It will always show the site a user has access to.
What exactly do you want to achieve?
Of course!
The main reason to know if this menu (appian native component) achieves the accesibility criteria for an accesibilty evaluation.
AFAIK Appian is doing a pretty good job in supporting accessibility. Either do a test or contact Appian for details.
Thanks!
