Tab disappears in formatted string in multiline text command

I would like to label a plot with a multiline formatted string which includes some tabs, but the tabs disappear on the plot. How to fix this? (I don't want to substitute spaces for the tabs since I am lining up colums in my real plot label).

Here's an example,

% Make example plot
f1 = figure;
peaks; 
view(2);
shading flat;
hold on;

% Create the string to label it with
str = sprintf('%6.4f\t\t%6.4f\nbbbbbbbbbbbbbb\nccccccccccc', rand(2,1));
disp(str) % Tabs are present

% Label the plot with string
t = text(-3, 0.4, str); % The text is labeled but the tabs have disappeared

t = text(-3, 0.4, detab(str));

Embarrasingly, I asked the same thing earlier. However now I am having trouble with detab in R2020a.

detab(str)
DETAB> file not found <>

ans =
     []

The comments in detab say the input should be a cell or a file. I will check into this.

@KAE: This is the documented behavior of this function: if the input is a CHAR vector, it is used as file name. Provide a cell string instead:

detab({str})
