Editing (inserting 3 beats into middle of song)

I’m using Audacity version 2.4.2 and Windows 10. I’m fairly new to Audacity so the answer may be right in front of me and I’m not seeing it.
I have a piece of music I’ve imported into Audacity and have even added a measure of click track to count me in. I’m recording the bass track to submit to our music director and he will mix all the files. Here’s the issue: He wants an additional 3 beats added into the middle of the song. Is there a way for me to add 3 click beats into the middle, thereby lengthening the song by 3 beats?
I think the capabilities are there but I haven’t been able to figure it out.

Split the track, then use time-shift tool
