How to add integer label in overlay or GUI?

IIRC there was <VAR:integer:ExampleName> in older version of Mcreator, so overlays could display numbers on screen

and now it seems that procedures handle this feature

this procedure simply returns value of string variable.

and this is a number one.

but why are there only string one on list? what should I do for putting number labels on screen in 2023.1?
