BlueSky API - Parsing Links & Text Decoration

Hello all! I’m building out part of a Scenario that will post content to my BlueSky account. I’ve been successful in setting up HTTP request modules and am able to create posts. The next phase of my build involves telling BlueSky how to decorate links. I need a way automatically identify links in the text string, specifically the ‘Start’ character and the ‘end’ character. I have regex that will identify the links I need to parse in the text string, but I’m not sure how to turn that into data that the BlueSky API will understand.
