Answer:
You were right it is intransitive, because I wouldn't say it was direct
Step-by-step explanation:
If it were direct than it would be thanked but techekly thanked is an transitive verb (does not allow a direct object. This is distinct from a transitive verb, which takes one or more objects.) so I would go with intransitive.
But I could be wrong ( I am 99% I am not wrong)
hope this helps!
