Ltac2: timeout tactic

Developing plugins
1

Dear community,

I would like to know if there is a native Ltac2 version of the timeout from Ltac1.

I have tried to use this tactic in Ltac2, but I get the Unbound value timeout error. For instance, the following example works:

Ltac timed_auto := timeout 60 (first [solve [auto] ] ).

but the following does not

Ltac2 timed_auto () := timeout 60 (first [solve [auto] ] ).

I have not found anything about this on the Ltac2 Wiki, and also not in the LTac2 Std library.
