! Forbidden control sequence found while scanning definition of

[pablgonz]

Hello, by adding in xsim.collections.tex

\RequirePackage[enable-debug]{expl3}
\ExplSyntaxOn
\debug_on:n { check-declarations , deprecation }
\ExplSyntaxOff
\usepackage{xsim}

Displays a number of errors, for example:

Runaway definition?
#1->\tl_set:Nx \l_tmpa_tl {\tl_trim_spaces:n {#1}}
! Forbidden control sequence found while scanning definition of \xsim_load_modu
le:n.

}
l.69     \str_if_eq_x:nnTF
                         { \l_tmpa_tl } {modules}
? 
! Undefined control sequence.
<argument> \LaTeX3 error: 
                '\str_if_eq_x:nnTF' deprecated on 2020-01-01. Use '\str_if_eq:e
l.69     \str_if_eq_x:nnTF
                         { \l_tmpa_tl } {modules}

I don't know if it's a false positive or maybe it needs some maintenance.
Greetings
