\begin{document}$ \alpha_D(b) $\end{document} and the angular position \begin{document}$ \theta_\infty $\end{document} decrease with increasing charge of the black hole Q, while the parameter γ displays opposite behavior to that of Q. By using observational data of supermassive black holes \begin{document}$ \mathrm{SgrA}^* $\end{document} and \begin{document}$ \mathrm{M}87^* $\end{document}, we obtain constraints for these parameters."> Theoretical study of Strong gravitational lensing around Dyonic ModMax black hole: constraints from EHT observations -
