Django: Current User Id for ModelForm Admin

I want for filter a ModelChoiceField with the current user. I found a solution very close that I want to do, but I dont understand Django: How to get current user in admin forms?

The answer accepted says

"I can now access the current user in my forms.ModelForm by accessing self.current_user"

--admin.py

class Customer(BaseAdmin):
    form = CustomerForm
    
    def get_form(self, request,obj=None,**kwargs):
        form = super(Customer, self).get_form(request, **kwargs)
        form.current_user = request.user
        return form

--forms.py

class CustomerForm(forms.ModelForm):
    default_tax =   forms.ModelChoiceField(
        queryset=fa_tax_rates.objects.filter(tenant=????)
    )

    class Meta:
        model   = fa_customers

How do I get the current user on modelchoice queryset(tenant=????) How do I call the self.current_user in the modelform(forms.py)

Just to sum up the solution because it was very hard for me to make this work and understand the accepted answer

In admin.py

class MyModelForm (forms.ModelForm):

    def __init__(self, *args,**kwargs):
    super (MyModelForm ,self).__init__(*args,**kwargs)
    #retrieve current_user from MyModelAdmin
    self.fields['my_model_field'].queryset = Staff.objects.all().filter(person_name = self.current_user)

#The person name in the database must be the same as in Django User, otherwise use something like person_name__contains

class MyModelAdmin(admin.ModelAdmin):
    form = MyModelForm 

    def get_form(self, request, *args, **kwargs):
        form = super(MyModelAdmin, self).get_form(request, *args, **kwargs)
        form.current_user = request.user #get current user only accessible in MyModelAdminand pass it to MyModelForm
        return form

Override __init__ constructor of the CustomerForm:

class CustomerForm(forms.ModelForm):
    ...
    def __init__(self, *args, **kwargs):
        super(CustomerForm, self).__init__(*args, **kwargs)
        self.fields['default_tax'].queryset = 
                        fa_tax_rates.objects.filter(tenant=self.current_user))

Queryset in the form field definition can be safely set to all() or none():

class CustomerForm(forms.ModelForm):
    default_tax = forms.ModelChoiceField(queryset=fa_tax_rates.objects.none())
