Ok. So, I found where I should get the Flow Definition value from. It came from previous Get Flow action.
But, after I add it, I got an error that says:

Request to XRM API failed with error: 'Message: Flow client error returned with status code "BadRequest" and details "{"error":{"code":"InvalidOpenApiFlow","message":"Flow save failed with code 'WorkflowRunActionInputsInvalidProperty' and message 'The 'inputs' of workflow run action 'Get Items' of type 'OpenApiConnection' should not have the property 'authentication'.'."}}".
Code: 0x80060467

I searched around and found a post which suggests to remove the authentication properties and so I did by converting the Flow Definition to string and replace the authentication property and it's value with empty string and then convert back to object using json() function.
However, after I removed all the authentication properties, I got another error related with connection references.

So, I insert Connection References from Get Flow action.
and I stumbled onto another error.
Right now I am completely stuck.
