Let $G$ be a Lie group acting on a manifold $M$. 

Consider the transformation groupoid $\mathcal{G}=(G\times M\rightrightarrows M)$.  We have the notion of de Rham cohomology of a Lie groupoid by considering de Rham cohomology of simplicial manifold associated to it, denoted by $\mathcal{G}_\bullet$.

Is there any relation between de Rham cohomology of Lie groupoid $\mathcal{G}$ (https://arxiv.org/pdf/math/0401420v3.pdf, page $11$) and the de Rham (??) cohomology of the Lie group $G$ and the de Rham cohomology of the manifold $M$?
