Ac clutch engagement?

[WhiteDiamondNemo]

2015 Yukon 5.3 .
Is there a way to get the compressor clutch to come on? I noticed there is no delay you can jump and I’m trying to fill to find my leak. Compressor clutch spins freely and no play, and condenser is recently replaced. Just want to fill it and run it with a dye to locate a leak but I am having a problem charging it at all. Any help is greatly appreciated and I did search but didn’t find anything similar.

i looked for the leak on our tahoe as follows.
The system was empty, then I filled it with nitrogen to 15 bar and then checked everything with a gas leak detector and found my leak at the LP and HP connections, then let the nitrogen out slowly again and then refilled.
