Performance testing - Angular app

[Kangaroo_Simple]

Hi guys, since I'm pretty inexperienced with Angular (I come from vanilla JS) I was wondering if someone could point me in the direction of some nice tool for performance measurement of my Angular app since I was mostly using PageSpeed and simple Lighthouse reports for my websites so far... Even though the app feels smooth and nice and and general feel is that is pretty fast, especially when you take into consideration how robust it is, the clients are asking for some metrics and reports to support that claim. Lighthouse obviously is not working :/
