Problem: the default typst references for math.equation labels appears as "Equation 1".
One may provide a supplement argument when referencing as in: <someEquation>[Eq.] which renders "Eq. 1" in the text.
However, this is insufficient for meeting the IEEE specification for equation references which should be rendered "(1)".
Solution: I modified the thmref function provided by typst-theorems (see here) in order to provide the level of customization necessary.
