How to write design and contrast in DESeq2 to find the up-regulated genes where the design have interactions

Hello
I have the following design in DESeq2: ~GT+TP+TP:GT . GT has two levels (K,W) . TP has two levels (0,2). I am looking for the genes that are up-regulated in samples where GT=W and TP=2. How do I define the contrast that these genes will have the highest log2FC.
Thank you
