[Copilot]

Pull Request Overview

This PR adds support for Tags in the Set-WellKnown script by introducing functionality to retrieve or create a tag and store its metadata in the wellKnown configuration object.

Key changes:

• Added a Set-Tags function to retrieve or create a tag via the Fabric REST API
• Integrated tag metadata (id, displayName, scopeType) into the wellKnown configuration

The code always selects the first tag from the response without validation. If the goal is to find a specific tag (e.g., 'Test Tag'), this should filter the results to match the expected tag rather than assuming the first tag is the correct one.

Suggested change

	$result = $results.Response.value[0]
	$result = $results.Response.value | Where-Object { $_.displayName -eq "Test Tag" } | Select-Object -First 1

[Copilot]

[nitpick] The hardcoded tag name 'Test Tag' should be extracted as a parameter or configuration variable to improve reusability and make the script more flexible.

Suggested change

	function Set-Tags {
	$results = Invoke-FabricRest -Method 'GET' -Endpoint "admin/tags"
	$result = $results.Response.value[0]
	if (-not $result) {
	$payload = @{
	createTagsRequest = @(
	@{ displayName = "Test Tag" }
	# Tag display name can be configured here
	$TagDisplayName = "Test Tag"
	function Set-Tags {
	$results = Invoke-FabricRest -Method 'GET' -Endpoint "admin/tags"
	$result = $results.Response.value[0]
	if (-not $result) {
	$payload = @{
	createTagsRequest = @(
	@{ displayName = $TagDisplayName }
