My guess is that they are fish eggs. Frog eggs are usually dark in color and fish eggs are mostly white.
If they have black in the center of each egg its frog
They are Insect eggs
They are called frog eggs
It's most likely to be fish eggs. Whatever they are, you should just leave them alone and let them grow so you can see what they are.
I think they are fish eggs because if you have fish in your pond and not frogs then I think it will be fish eggs plus frog eggs are like stuck to plants
