How to change MudExpansionPanel's initial state to an expanded state using MudBlazor?

I have created a simple expansion panel using MudBlazor and included it below.

<MudExpansionPanels><MudExpansionPanel><TitleContent><div class="d-flex"><MudText>Expansion Panel</MudText></div></TitleContent><ChildContent>            Panel Content</ChildContent></MudExpansionPanel></MudExpansionPanels>@code{}

The default state of the expansion panel is Collapsed. Now I have needed to change its default state as the expanded state. It means when I start the application by default it should be expanded. How to do this using blazor??
