### Description

Recent measurements of $B$-meson decays show a consistent pattern of tensions between measured observables and Standard Model (SM) predictions. These tensions are referred to as the flavour anomalies. To understand the source of these anomalies, measurements of $b\to$$s\tau^{+}\tau^{-}$ processes are paramount, as many New Physics explanations favour enhancements in this mode. Of particular interest is the decay $B^0$$\to$$K^{*0}\tau^+\tau^-$. Reconstructing tau final states is however challenging and no measurement of $\mathcal{B}(B^0\to$$K^{*0}\tau^+\tau^-$) has been made to date. This talk/poster outlines a novel approach to measuring $\mathcal{B}(B^0\to K^{*0}\tau^+\tau^-)$ via the non-local double-loop process $B^0$$\to$$K^{*0}\tau^+\tau^-(\to$$\mu^+\mu^-)$. The analysis strategy is outlined, including the expected sensitivities to $\mathcal{B}(B^0$$\to$$K^{*0}\tau^+\tau^-)$ using this approach.
