Tycho Brahe was a nobleman and a difficult character, and it would have been beneath his dignity to 'work together' with Kepler, one of his employees. Most of Kepler's work was done after Brahe's death when he gained access to the figures from Brahe's detailed high-quality measurements.
Kepler used the measurements and assumed the heliocentric idea - the Sun at the centre - to produce his three laws of planetary motion. Many years later Newton's discoveries of the laws of motion and the law of gravity, plus his use of differential calculus, showed why Kepler's laws are as they are, and the heliocentric theory was later generally accepted.
Kepler used Tycho Brahe's data to establish the heliocentric theory of the solar system.

Galileo did not have his own theory. He was a supporter of Copernicus's heliocentric theory and an opponent of the geocentric Ptolemaic theory. Eventually both theories were rejected in favour of Kepler's theory. But Kepler's theory uses the heliocentric idea from Copernicus's theory.
Kepler improved upon Copernicus's heliocentric model by introducing elliptical orbits, demonstrating that planets do not move in perfect circles but rather in ellipses, which better explained their observed motions. Galileo complemented this by providing observational evidence through his telescope, such as the phases of Venus and the moons of Jupiter, which supported the Copernican view and challenged the geocentric model. Together, their contributions helped solidify the heliocentric theory and laid the groundwork for modern astronomy.
The heliocentric theory, which posits that the Earth and other planets revolve around the Sun, originated in the 16th century. It was proposed by astronomers such as Nicolaus Copernicus and further developed by Galileo Galilei and Johannes Kepler during the Scientific Revolution.

Kepler completely replaced Copernicus's theory of the orbits of the planets, which was based on circles an epicycles, with a new theory using elliptical orbits. However Kepler retained Copernicus's idea of placing the Sun at the centre.

copernicus coined the heliocentric theory...

The heliocentric 'theory' is not really a theory at all, more an assertion that the Sun is at the centre of the solar system. Copernicus's theory assumes that the Sun is at the centre and provides a model of the planets' orbits that uses circles and epicycles to explain the observed orbits. He said it was simpler than the old "geocentric" (Earth centred) Ptolemaic system, but it was not really, it actually had more epicycles. Note: Perhaps the questioner got mixed up. The Copernican theory IS a heliocentric theory. Perhaps the question is about the geocentric theory and the Copernican theory. Anyway, Kepler simplified the heliocentric theory and now we know that his model is correct.
The heliocentric theory is the theory that the sun is the center of the universe, not the earth.
