Pull request overview

This PR adds SMS clicks to the list of interaction data used by Intelligent Timing to calculate optimal send times for users. The change accurately documents that SMS clicks are only included when link shortening with advanced tracking is enabled, which aligns with the existing documentation on the link shortening feature.

Key Changes

• Adds "SMS clicks" as a new data point that Intelligent Timing uses to determine optimal send times
• Includes a conditional note explaining that this only applies when link shortening and advanced tracking are enabled
• Provides a link to the link shortening documentation for additional context

[Copilot]

The word "clicks" should be capitalized to maintain consistency with the other list items. The list uses "Email Clicks" and "Email Opens", so this should be "SMS Clicks" (capital C).

Suggested change

	- SMS clicks (only if [link shortening]({{site.baseurl}}/user_guide/message_building_by_channel/sms_mms_rcs/link_shortening/) and advanced tracking are enabled)
	- SMS Clicks (only if [link shortening]({{site.baseurl}}/user_guide/message_building_by_channel/sms_mms_rcs/link_shortening/) and advanced tracking are enabled)
