How to programmatically get a list of tasks from a document in 1C 8.3 workflow?

Question

Document flow

Hello.
Installed 1s workflow 8.3. No changes were made to the configuration. All business processes are configured through the user interface.

Please tell me how to programmatically get a list of tasks that a document has.
I find the document using the query:

выбрать * из Справочник.ВнутренниеДокументы КАК док где док.РегистрационныйНомер = &ном

But there are no tasks.
Found some problems here

ВЫБРАТЬ первые 100 *
ИЗ БизнесПроцесс.Исполнение КАК Исполнение 
Упорядочить по  Дата Убыв

But I don't know how to connect.

You need to find which BP was created, then the list of Tasks that it initiated.
For example, open the Internal Document card, it displays BP and Tasks.
SELECT
Contractor Task.BusinessProcess,
Contractor Task.Reference
FROM
Task.Executor Task AS Task Contractor
