Gigantic quarter note break

Any suggestion how to make an gigantic quarter note break (See red circle enclosed)

an insert it between the 2 actions from the start

I’d add it as text… (Even as a separate text frame in the layout, if necessary…)

Sorry if daft,
You mean ? find the font accordingly having a rest inside, Dorico finale etc and then insert it as an text in the file ?

Right click in the Text editor to select music characters.
