How do you format Tags in Zapier?

I sent the following message to Monday support and they said to post here:

I’m trying to use Zapier to create items in one of my boards from Slack messages and to add a tag to the newly created item in Monday. I have tried using the tag ID and tag name in Zapier but get an invalid value error for the tags column. How do you format tag values in Zapier?

I have tried using the Tag name, Tag ID, and the {“tag_ids” : [295026]} formatting shown in this doc and receive the same error for all three.

Zap setup:

  1. New Message Posted in Slack Channel
  2. Create item in
  3. Change multiple columns value in
