Validation in: Laravel 8

I am trying to validate that the data selected from a select is in the "categories_condominiums" table and in the "category" column since the user could change the html code, I do it with this FormRequest rule:

'categoria_condominio' => 'in:categorias_condominios,categoria|required',

And this is the table where it does the condo_categories check:

But whichever one I choose, it gives me the error:

Mistake! The selected condo category is invalid.
