How can I replace placeholder-text in a .msg file

Hello! Im trying to figure out how I can use UiPath to replace this text:

Hi @Job_Vermeulen which text you are trying to replace with Uipath can you please elaborate what you are trying to say.

String Variable.replace(“target value or text”,“what output value need”)

@Job_Vermeulen

have a Look on it->

So basically I want to change the “{{name}}” below with a value. Basically I want to let UiPath scan the text and replace anything that matches the criteria “{{name}}” to a value I give in earlier in the same formatting. Do you know what steps I should use?
