SmartThings does not provide lighting effects, it doesn’t even provide support for vendor scenes.
However, you can use virtual switches connected to Google Home to, indirectly, activate scenes of WiZ and, I guess, Govee and others. It’s what I use for my WiZ scenes.
If that’s not an option or you want it fully local you’ll have to build your own effect, but that can be cumbersome. And if you want something smooth like the native dynamic modes where the colour is constantly changing in a seamless way you’ll have to use custom drivers. Stock drivers can’t do Zigbee / Matter colour transitions.
Should you follow the build your own effect path…
For Zigbee lights, you can use this driver, I’ve not tested it since I don’t have Zigbee lights but many users have.
For Matter lights you can use my driver, I tested the colour animations of the examples in WiZ and IKEA lights. The driver offers the tools to build transitions and control the randomization of colours so you can have some fun looping them.
