I found this line

ul class="o_menu_systray" role="menu"

here  \https://github.com/odoo/odoo/blob/1ddca13295bb9bf530ddb062066e2b006913adc3/addons/web/static/src/xml/menu.xml#L9

(copy that link manually because this forum is horrible and it keps breaking the link)

when I remove it it removes systray menu for all users ofc. Can I make systray somehow hidden based on groups?

Specifically I want it to be hidden for portal users.
