How to print all possible options of a dropdown field inside of a Matrix field? I'm asking this outside an entry context.

My starting point is 


  {% set field = craft.app.fields.getFieldByHandle('matrixFieldHandle')
  %}


When I print the data of the field, I find nothing related to the fields that matrixFieldHandle contains.


matrixFieldHandle (Matrix field)


Block Log


Field logValue (Dropdown field)




I know how to print the options in a dropdown field:


How do I output a dropdown&#39;s values if I&#39;m on a registration form not tied to an entry?
How do I print the options in a dropdown field?


But how can I print all these dropdown options when it is set inside a Matrix?
This can be done like so...

{% set matrix = craft.app.fields.getFieldByHandle('myMatrixField') %}
{% for field in matrix.blockTypeFields if field.handle=='myDropdownField'  %}
    &lt;select&gt;
    {% for option in field.options %}
        &lt;option value="{{ option.value }}"&gt;{{ option.label }}&lt;/option&gt;
    {% endfor %}
    &lt;/select&gt;
{% endfor %}
