Using SharePoint Lists to display Parent/Child Relationships via a lookup ID in Powerapps

[olsen9]

List A shows items in powerapps, would like a Tab at the top that shows the 1 to many relationship in List B when clicking the Tab it opens List B items that have the same Lookup ID from List A.  I've seen someone do this with a 1 to 1 but not sure on the new form to show List B when selecting the Tab what would be the syntax to show all items related.

Screen 1:

Gallery1 - linked to main Data Source

Screen2

Gallery 2 - "Items" - filter(<data source>, LinkedID = Gallery1.selected.ID)

Is this the information I add to the button that will look like a tab?

It doesn't work since my list A is not a Gallery, just a SharePointForm1

so the filter is now working in my new gallery, the only piece I need to update is the button to show this filtered gallery.  I've tried Launch(browsegallery1) but not working

figured it out with the navigate option.  thanks for the help on the filters.
