unable to "Displaying a popup via a script" if i use "this" as the deviceID in the scrip, but it is working fine if i use the browser's deviceID directly.

i use the same sample in the Cookbook.

i was unable to "Displaying a popup via a script" if i use "deviceID: this" as the deviceID in the script, even i run the script directly. But it is working fine if i use the browser's deviceID directly ,
for example" deviceID: 3ads72oj-3jf87rdm"

May be HA cannot recognize "this" of the deviceID in the script???

test_popup:
sequence:
- service: browser_mod.popup
data_template:
deviceID: this <<<< cannot
deviceID: 3ads72oj-3jf87rdm <<<< can
title: Testing script
card:
type: entities
entities:
- light.bed_light

The script runs on your server and can't know which browser you are currently using.
