I have windows

i installed odoo16 with installer 

get my plugin from git and clone it in   

'C:/Program Files/Odoo16/server/addons',

'C:/Program Files/Odoo16/server/odoo/addons',

but after restarting the service :

I can't see my addons like odoo15

I can't find a refresh list of add-ons action buttons like odoo15

i added my custom addon path here:

and restart the service but add-ons didn't show in app list
