Create a Delete button to delete checked gallery items

[Ardions]

Dears,

I have a gallery connected to a SharePoint list in my app. I added a checkbox(CBGallery) per item in the gallery and one check box that checks all boxes in the gal(CB_checkall) outside the gallery.
At the moment I have one button to assign Team Leads to a group of people. Here's my onSelect:
Patch('Quality evaluator',ForAll(Filter('Gal-schedule'.AllItems,CBGallery.Value) As _item1,{ID: _item1.ID,'First evaluator':'combobox.evaluator_3'.Selected,'Status evaluation': "Pending"}))

I want to add a delete button that will delete the items I checked with my checkbox but I'm not being able to do it. Can you help?

@Ardions 

Please consider the following Formula:

ForAll(
    Filter('Gal-schedule'.AllItems,CBGallery.Value) As _item1,
    RemoveIf('Quality evaluator', ID= _item1.ID)
)

I hope this is helpful for you.
