@Loonuh Probably the reason the above didn't work for you is the -b 2 which says use 2nd band and you had a multiband image. The number should be changed to match the Alpha band created in step 1. Also see the related gis.stackexchange.com/a/408628/108, which shows an example of scaling all data values into a single group.

Fix typo for alpha flag in step 1.
