change the justification of a mtext in vlisp

[Dr.Lube]

Bye!
fast question, unfortunately I did not find anything on the net. .

I should change the justification of a mtext from "high left" to "centered".

I can't find what I need.

(vlax-dump-object obj)
; iacadmtext: interfaccia autocad mtext (testom)
; valori della proprietà:
;   application (ro) = #<vla-object 000000013fc59110="" iacadapplication="">
