drasszkusz confirmed that the question is solved:
Dear Jérôme and Robert,

thank you for your responses.

>> Maybe you can try starting from Raphael's PhD Thesis, § 2.1.3 of
[Maurin2015PhD, *]...

Yes, it confirms the same as it is in the GlobalStiffnessTimestepper
manual. The references in that study were also a dead end.

>>  The timestep associated with viscoelastic dampers-case is estimated
using identical logic to the stiffness-only case.
GlobalStiffnessTimestepper computes both and uses the smallest one. This
is apparent by working backwards from [1], and is confirmed by Jérôme's
link on page 18.

In that case I have to reengineer the formula of the viscous part from
the source code or search the internet for other studies. Because the
references you provided only describe the elastic parts and just mention
the viscous critical time step. Only the elastic formula can be found
written down.

Cheers,
D
