how to use domain:complex$ command in sagemath for maxima?

edit

A Basic question:

I need to run integrals in maxima using sagemath, but I need to set the domain to complex first, since default in maxima is real domain.

In Maxima itself, the command is

domain: complex$

I am newbie in Maxima and sagemath and could not find the answer googling so far. What command should one issue, from inside sagemath, before calling integrate, to tell maxima to use complex domain? What is the syntax to use?

I do not want to use assume command on some specific symbols, but I want to tell maxima to use the complex domain for all symbols involved.

Thank you
