How to draw the new tensor lineset with color?

[EwingKang]

Hello,
I want to draw a colored lineset using the newer, Tensor version of the geometry.
However, with following code, all the lines in the visualizer are still black. Is this the correct way to do this? I think the legacy version worked according to this quesion in the previous python version.

auto lineset_aaa = std::make_shared<open3d::t::geometry::LineSet>(vertices, v_idxs);
Eigen::MatrixXf line_clr(v_idxs.size(), 3);
line_clr.rowwise() = Eigen::Vector3f(0.5, 0.5, 0).transpose();
lineset_aaa->SetLineColors( o3d2eigen::EigenMatrixToTensor(line_clr) );

std::vector<o3d_v::DrawObject> draw_objs;
draw_objs.push_back(o3d_v::DrawObject("rays" lineset_aaa, true));
open3d::visualization::Draw(draw_objs, "ShowLine");

I couldn't replicate the problem. It seems to have some leaks in my testing code. Closing the issue.
