Filter = Field from Logged User custom field

Frappe Framework Customization

I am trying to get & apply a filter from logged user’s custom field “City”,
So in sales invoice list view, data in logged user’s field city will be set as filter. (No user permission but just a filter require)

How to get exact filter data from logged user? This is how I am trying from sales_invoice_list
