Microsoft Power Automate Flow Trigger Conditions

Two Compose actions are added to show the values of the Content Type and Example properties of the triggering items. When the Test functionality is used, three scenarios can be run:
Item Content Type:
Create a new Item which has only the Title column; no processing should occur.
Item 2 Content Type Without Example Value:
Create a new Item 2 which has both Title and Example columns, complete only the Title; no processing should occur.
Item 2 Content Type With Example Value:
Create a new Item 2 which has both Title and Example columns, complete both; the Test
