Abstract
The constituents of dark matter are still an unresolved puzzle. Several Beyond Standard Model (BSM) Physics offer suitable candidates. In this study here we consider the Two Higgs Doublet model augmented with a complex scalar singlet (2HDMS) and focus on the dark matter phenomenology of 2HDMS with the complex scalar singlet as the dark matter candidate. The parameter space allowed from existing experimental constraints from dark matter, flavour physics and collider searches has been studied. The discovery potential for such a 2HDMS at HL-LHC and at future $e^+e^-$ linear colliders has been worked out.

Reports on this Submission
Strengths
1. The manuscript studies the dark matter phenomenology in the Higgs double model with an additional singlet with collider and direct/indirect detection bounds.
Weaknesses
Given the large number of free parameters, it is difficult to obtain conclusive results, or to provide more insights, for dark matter search.
Report
The study is solid, and provides enough constraints for this model , meeting the criteria of SciPost Physics Proceedings. So it can be published after several minor changes are made.
Requested changes
1. The parameters adopted for Fig.1 seem missing. The author should add the information here, otherwise, the reader can hardly get any information from the figure. A comment on Fermi-Lat bound would be nice, as the author claims that it is included.
2. Notations should be used consistently, such as "\emph{vev}" and "vev", also "missing ET" . BTW, all values of $\lambda$ should be real numbers (from Table I), why they have imaginary expressions just above section 2.2?
3. I strongly suggest the author improve the text, especially the last paragraph in Introduction.
