Add grouping to mat-table on Angular. Stackblitz provided. -- 2

This is an Angular 14 request, just need someone to combine two features into one stackblitz project. You dont need to develop a new feature. I have a mat-table with some filtering, I need to add a grouping feature that I found and its working in a separate stackblitz. Just want to have the grouping feature on the mat-table with the filtering. Stackblitz with filters: [login to view URL] Stackblitz with grouping: [login to view URL],src%2Fapp%[login to view URL],src%2Fapp%[login to view URL] I want a merge of both, it can be in any of the two existing stackblitz projects. no need to create a new one. This is urgent so I hope someone can do it within 5 hrs max
