I learn best by seeing how a working mod is done & learning to adapt it.

This is for Java 1.20.4
Sorry about the long post.

Here is what I have so far:

1. 
   found an old datapack / resource pack on here called More Animals
   
2. 
   it only works on an older MC version
   
3. 
   contacted mod maker... no response.
   
4. 
   Asked someone on here for help, got a wonderful response to fix my problem.
   

Its for an Alice in Wonderland project.
Pic shows a Flamingo upside down as a croquet mallet.
It adds the model to an invisible armor stand.
Nothing fancy or animating.





Here's what I know:

1. 
   I know how to make a Blockbench .json model
   
2. 
   I know where to put the model & texture files.
   
3. 
   I know what the nice guy did to make it work.
   

Here is what the guy did:
In the datapack, he added a commands.txt file


/give @s axolotl_spawn_egg{EntityTag:{id:"minecraft:armor_stand",Silent:1b,Invulnerable:0b,Invisible:1b,Small:1b,Marker:1b,ArmorItems:[{},{},{},{id:"minecraft:flint",Count:1b,tag:{CustomModelData:42}}]}}




My questions:

1. 
   The model is named flam1.json
   How does the command above: CustomModelData:42 point to it?
   
2. 
   How do I add another GIVE line to the commands.txt?
   Do the 2 GIVE commands just need to be on 2 separate lines?
   A Colon or Semi-Colon between them?
   
3. 
   Is there anything else in the GIVE line I need to change so they don't conflict?
   

Once I have the HOW TO on adding more models, I can make a demo / how-to and put it online for others to know how.
