FA5 workflow:
```
➜  user.workflow.4543DB6D-4242-402A-9A4B-D3C71FC1C4CC ./faw put --name f1f8
fa-trash%                                                                                                                                       ➜  user.workflow.4543DB6D-4242-402A-9A4B-D3C71FC1C4CC

➜  user.workflow.4543DB6D-4242-402A-9A4B-D3C71FC1C4CC ./faw put --code f1f8
f1f8%                                                                                                                                           ➜  user.workflow.4543DB6D-4242-402A-9A4B-D3C71FC1C4CC

➜  user.workflow.4543DB6D-4242-402A-9A4B-D3C71FC1C4CC ./faw put --url f1f8
https://fontawesome.com/icons/trash%            
                                 
➜  user.workflow.4543DB6D-4242-402A-9A4B-D3C71FC1C4CC ./faw put --ref f1f8
trash%
```

If I understand everything correctly, this one is incorrect:
```
➜  user.workflow.4543DB6D-4242-402A-9A4B-D3C71FC1C4CC ./faw put --ref f1f8
trash%
```

Fa4 workflow:
```
user.workflow.EC9AE299-805D-4336-82B6-8A7A2699306C ./faw put --ref f1f8
%
```
