There are multiple methods to look at poorly performing queries in SQL Server, notably Query Store, Extended Events, and dynamic management views (DMVs). Each option has pros and cons. Extended Events provides data about the individual execution of queries, while Query Store and the DMVs aggregate performance data. In order to use Query Store and Extended Events, you have to configure them in advance – either enabling Query Store for your database(s), or setting up an XE session and starting it.
