The project uses Helix publishing and all the Sitecore dlls are excluded, in the publishing targets file.
<ItemGroup>
<SitecoreAssembliesToExclude Include="@(SitecoreAssemblies)" />
</ItemGroup>
<ItemGroup>
<ExcludeFromPackageFiles Include="bin\Sitecore.*.dll" />
<ExcludeFromPackageFiles Include="bin\*.dll.config" />
<ExcludeFromPackageFiles Include="bin\*.pdb" />
<ExcludeFromPackageFiles Include="bin\Scriban.dll;bin\Spatial4n.Core.dll;bin\Newtonsoft.Json.Bson.dll;bin\Microsoft.OData.Client.dll;bin\AjaxMin.dll;bin\Microsoft.Extensions.Caching.StackExchangeRedis.dll" />
<ExcludeFromPackageFolders Include="bin\de" />
</ItemGroup>
<PropertyGroup>
But I want to include this dll - Sitecore.Commerce.ServiceProxy
