Popup OriginPoint coming from TabBar for reasons?

[swimnbird]

I have a situation to where the origin of the pop over is coming from my tab bar instead of the button itself. I assume this must be because I have the button within a PageViewController.
Possibly I should be using something other than 'sender.frame', but I don't know what.

    @IBAction func button1Action(_ sender: UIButton) {
        
        
        //Origin Point
        let originPoint = CGPoint(x: sender.frame.midX, y: sender.frame.maxY + 158) //(Y = down)
        
        let popoverView = UIView(frame: CGRect(x: 32, y: sender.bounds.maxY + 20, width: self.view.bounds.width - 64, height: 200))
        
        let textLabel = UILabel(frame: CGRect(x: +15, y: 0, width: popoverView.bounds.width - 15, height: popoverView.bounds.height))
        
        textLabel.lineBreakMode = .byWordWrapping
        textLabel.numberOfLines = 0
        textLabel.textColor = .white
        textLabel.text = "Use neutral framing of the events rather than perceptually colored language. eg:\n\n____ event occured.\n____ person said: '____'.\n____ object was altered in ____ way."
        textLabel.textAlignment = .left

        
        popoverView.addSubview(textLabel)
        
        
        let options: [PopoverOption] = [
            .cornerRadius(25),
            .color(.systemTeal)
        ]
        
        let popover = Popover(options: options)
        popover.show(popoverView, point: originPoint)

    }
