Developing masks to a Landsat composition

Question

I'm a beginner at GE and JavaScript code. I want to apply two masks to a Landsat composition that is already done in the code.

First I've done the raster upload (that I want to be a mask), which I called "image1". Second, I want a mask that will delete pixels that are smaller than 1 ha.

The mask doesn't appear in the final result, where is the problem?

var mascara = function (image) {
  // Develop masks for anthropized area.
 var qaMaska = image1.select("b1")
 return image.updateMask(qaMaska)
}

var pixels = function (image) {
// Develop masks for pixels larger than 1000 ha.
var minArea = 10000
var maxSize = 200
var pixelCount = hx.connectedPixelCount(maxSize)
var minPixelCount = ee.Image(minArea).divide(ee.Image.pixelArea())
var agricFin = hx.updateMask(pixelCount.gte(minPixelCount))
}
