Ok first of all is a .js file but you can compress it, second of all it's a broken dropbox link and last but not least BlockLauncher only works for 1.12-1.14 so 1.16 can't use the debug stick
Unfortunately, no. The ModPE(I mean it’s not Pocket Edition anymore) script needs a third part application to run it, this is currently only avalible to Android devices.
2: Blocklauncher does not work on the latest version of minecraft please make it a .mcaddon file
