Insert a callout-block div of type 'note', which has a blue accent and a letter 'i' icon. Will embed text selected bythe user, otherwise skeleton help text will be inserted.
Details
The output looks like this if the user hadn't selected any text:
:::{.callout-note collapse=false appearance='default' icon=true}
## Optional caption (note)
- Hide callout body with 'collapse=true'
- Remove 'collapse' to prevent expandability
- Set appearance to 'default', 'simple' or 'minimal'
- Remove icon with 'icon=false'
