Filter tag and category

Hi i'm new with your templating, I want to show the post of these tag (cooking) and terms(Active)

ISSUE #1: Get post tag "cooking" and terms of "active")

{% set args = { post_type: "brand", posts_per_page: 4, tag: "cooking", tax_query: [ { taxonomy: 'brand-category', field: 'slug', terms: 'Active' } ] } %}
				
{% set posts = mb.get_posts( args ) %}
{% for post in posts %}	

{% endfor %}

ISSUE #2: I want to get post of these two categories "Active" and "Excited"

{% set args = { post_type: "brand", posts_per_page: 4, tax_query: [ { taxonomy: 'brand-category', field: 'slug', terms: 'Active' }, { taxonomy: 'brand-category', field: 'slug', terms: 'Excited' } ] } %}
				
{% set posts = mb.get_posts( args ) %}
{% for post in posts %}	

{% endfor %}

Thank you
