In this work, we study microlensing effects in strongly lensed gravitationalwave (GW) signals corresponding to global minima in galaxy-scale lenses. Wefind that stellar microlenses alone are unable to introduce noticeable waveeffects in the global minima GW signals at strong lensing magnification$(\mu)<50$ with match value between unlensed and lensed GW signals being above${\sim}99.5\%$ in ${\sim}90\%$ of systems. Since the stellar microlensesintroduce negligible wave effects in global minima, they can be used to probethe intermediate-mass black hole (IMBH) lenses in the galaxy lens. We show thatthe presence of an IMBH lens with mass in the range $[50,10^3]~{\rm M_\odot}$such that the global minima lies within five Einstein radius of it, themicrolensing effects at $f<10^2$ Hz are mainly determined by the IMBH lens for$\mu<50$. Assuming that a typical strong lensing magnification of 3.8 and highenough signal-to-noise ratio (in the range $\sim[10, 30]$) to detect themicrolensing effect in GW signals corresponding to global minima, withnon-detection of microlensing effects in ${\sim}15 ({\sim}150)$ lensed GWsignals, we can rule out dark matter fraction $>10\% (>1\%)$ made of IMBHpopulation inside galaxy lenses in mass range $[50, 10^3] {\rm M_\odot}$ with${\sim}$90\% confidence.
