Addon for Classic to use /in command in a Macro

I’ve read that the /in command to delay text in a macro does not work by default in Classic, but that there are addons that make it possible. I was wondering if anyone has a link to one because I’ve only been able to find ones that are for vanilla private servers. Or if anyone knows another way around this problem that would work as well. What I’m trying to do is pretty simple:

#showtooltip
/cast Last Stand
/y Last Stand used!
/in 15
/y Last Stand fading in 5 seconds!

something along those lines, and a pull timer would be nice to have as well.

Thanks in advance and sorry if this is posted elsewhere!

perfect tysm.

quoted thread with OP within 2hr of mine. for shame
