Adobe Sign Text Tag for bolding default text

Greetings community,

I am creating a form where a default text will appear based on a condition and would like this text to stand out by being bold. I am having difficulty figuring out the correct text tag to do this. The Adobe Sign Text Tag guide says you can format text using the outer {}, however, when I make these bold it does not carry over to the form (this also doesn't work for font color - maybe an opportunity to review guide).  The other part of the guide coveing format gives this example: f2_es_:signer1:calc(formula):format(formatType, format). However, I do not know what to put in the formatType and format to get the text to bold.

Is there a text tag to allow me to have default text be bold.

The code I have is: 

{{#ia1=!ia1_es_:signer1:multiline(2):default(“STOP: If you are uncertain of the process or what is expected of you with completing the intake form, call... .”):showif(a7=no)}}
