Need help on Limbdi to Dwarka transportation

I’ll be attending a wedding in Limbdi in February, and afterward I’m planning to visit Dwarka. I checked the GSRTC app, but it doesn’t show any buses on this route. What’s the best way to reach Dwarka from Limbdi?

I’m planning to travel on 11th February. I also have a return flight to Bangalore on the 13th or 14th—will I be able to cover both Dwarka and Somnath within this timeframe?
