Legacy gas fee estimation

[dxxzero]

I am currently testing a created web app which uses web3.js. When I am trying to send a transaction, I receive following warning message:

Before continuation, I need to manually change the gas fee. Is there a way to use another gas calculation, so that the webapp correctly calculates the fee?

Currently it calculates it way too low.

Which web application are you using?

[dxxzero]

It's just a plain HTML page which includes the .js file and calls a contract function:

await window.contract.methods.testFunction().send({ from: account, value: web3.utils.toWei('0.03', "ether") });

The .js file is included like this:

 <script src='./web3.min.js'></script>
