: The research adhered to the following instructions: (1) all participants were explained about the study and its procedures before taking the survey; (2) the research uses a simple questionnaire that collects non-identifiable data about participants (i.e., without name, address, or affiliation); (3) the research maintained absolute confidentiality of the obtained data; and (4) the questionnaire and methodology of this study have been evaluated as appropriate by the author’s institution. However, this type of research does not require ethical approval as it does not contain sensitive or private information. Ethical approval was therefore not provided, and the author’s institution did not issue an ethical number.
: The authors sought and obtained Informed consent before and throughout the data collection process. The participants were informed that their participation was voluntary and that all information was treated with confidentiality and anonymity. Moreover, this research did not collect identifying details such as names, addresses, or affiliations. The participants were also made aware of their right to withdraw from the survey at any time, and they were asked to check the consent box before completing the survey.
