You can delete a record in Dataverse from a Power Apps Canvas App by using the Remove function. Here's a formula example that demonstrates how you might delete a specific record:
Remove('Your Dataverse Table Name', LookUp('Your Dataverse Table Name', ID = varSelectedRecordID))
In this example, 'Your Dataverse Table Name' should be replaced with the name of the table in Dataverse where you want to remove the record.
The varSelectedRecordID would be the specific ID of the record you want to delete.
Make sure you replace these placeholders with the actual table name and record ID relevant to your scenario.
If you have a specific gallery, and you want to remove the selected item from that gallery, you might use:
Remove('Your Dataverse Table Name', ThisItem)
Here, ThisItem refers to the currently selected item in the scope of the gallery.
You may also use a Table to remove multiple Records rather than one single Record.
